General DescriptionThe MAX200–MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication inter-faces where ±12V supplies are not available. On-board charge pumps convert the +5V input to the ±10V need-ed for RS-232 output levels. The MAX201 and MAX209operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.The MAX200–MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a data rate of 20kbps. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification.The 5µW shutdown mode of the MAX200, MAX205,MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shut-down and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indica-tor (RI) to be monitored easily using only 75µW power.The MAX211 and MAX213 are available in a 28-pin wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now avail-able in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components,and are recommended for applications with limited circuit board space.ApplicationsComputersLaptops, Palmtops, Notebooks Battery-Powered Equipment Hand-Held Equipment Next-Generation Device Features ♦For Low-Cost Applications:MAX221E: ±15kV ESD-Protected, +5V, 1µA, Single RS-232 Transceiver with AutoShutdown™♦For Low-Voltage and Space-Constrained Applications:MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: ±15kV ESD-Protected, Down to 10nA,+3.0V to +5.5V, Up to 1Mbps, True RS-232Transceivers (MAX3246E Available in UCSP™Package)♦For Space-Constrained Applications:MAX3228E/MAX3229E: ±15kV ESD-Protected,+2.5V to +5.5V, RS-232 Transceivers in UCSP ♦For Low-Voltage or Data Cable Applications:MAX3380E/MAX3381E: +2.35V TO +5.5V, 1µA,2Tx/2Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins ♦For Low-Power Applications:MAX3224E–MAX3227E/MAX3244E/MAX3245E:±15kV ESD-Protected, 1µA, 1Mbps, +3.0V to+5.5V, RS-232 Transceivers with AutoShutdown Plus™MAX200–MAX211/MAX213+5V , RS-232 Transceivers with 0.1µF External Capacitors ________________________________________________________________Maxim Integrated Products 119-0065; Rev 6; 10/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information appears at end of data sheetAutoShutdown, AutoShutdown Plus, and UCSP are trademarks of Maxim Integrated Products, Inc.MAX200–MAX211/MAX213+5V , RS-232 Transceiverswith 0.1µF External Capacitors______________________________________________________________________________________19Ordering Information*Contact factory for dice specifications.M A X 200–M A X 211/M A X 213+5V , RS-232 Transceiverswith 0.1µF External Capacitors Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.

General DescriptionThe MAX4580/MAX4590/MAX4600 dual analog switches feature low on-resistance of 1.25Ωmax. On-resistance is matched between switches to 0.25Ωmax and is flat (0.3Ωmax) over the specified signal range. Each switch can handle Rail-to-Rail ®analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automat-ic test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.The MAX4580 has two NC (normally closed) switches,the MAX4590 has two NO (normally open) switches,and the MAX4600 has one NC (normally closed) and one NO (normally open) switch.These switches operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +12V sin-gle supply or ±15V dual supplies.ApplicationsReed Relay Replacement Test EquipmentCommunication Systems PBX, PABX SystemsFeatureso Low On-Resistance (1.25Ωmax)o Guaranteed R ON Match Between Channels (0.25Ωmax)o Guaranteed R ON Flatness Over Specified Signal Range (0.3Ωmax)o Rail-to-Rail Signal Handlingo Guaranteed ESD Protection >2kV per Method 3015.7o Single-Supply Operation: +4.5V to +36V Dual-Supply Operation: ±4.5V to ±20V o TTL/CMOS-Compatible Control InputsMAX4580/MAX4590/MAX46001.25Ω, Dual SPST,CMOS Analog Switches________________________________________________________________Maxim Integrated Products119-1394; Rev 1; 6/03Ordering Information continued at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.Pin Configurations/Functional Diagrams/Truth TablesOrdering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4580/M A X 4590/M A X 46001.25Ω, Dual SPST,CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+and V- should not exceed 44V. These protection diodes are not recommended when using a single supply.Figure 1.

MAX809 Series,MAX810 SeriesVery Low Supply Current 3-Pin Microprocessor Reset MonitorsThe MAX809 and MAX810 are cost–effective system supervisor circuits designed to monitor V CC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.The reset output is driven active within 10 µsec of V CC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140 msec after V CC rises above the reset threshold. The MAX810 has an active–high RESET output while the MAX809 has an active–low RESET output. The output of the MAX809 is guaranteed valid down to V CC = 1.0 V. Both devices are available in a SOT–23 package.The MAX809/810 are optimized to reject fast transient glitches on the V CC line. Low supply current of 1.0 µA (V CC= 3.2 V) makes these devices suitable for battery powered applications.Features•Precision V CC Monitor for 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies •Precision Monitoring V oltages from 1.6 V to 4.9 V Availablein 100 mV Steps•140 msec Guaranteed Minimum RESET Output Duration •RESET Output Guaranteed to V CC = 1.0 V•Low Supply Current•V CC Transient Immunity•Small SOT–23 Package•No External Components•Wide Operating Temperature: –40°C to 105°CTypical Applications•Computers•Embedded Systems•Battery Powered Equipment•Critical µP Power Supply MonitoringV CCFigure 1.

Figure 2 shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive which lies under the curve will not generate a reset signal. Combinations above the curve are detected as a brownout or power–down. Typically, transient that goes 100 mV below the reset threshold and lasts 5 µs or less will not cause a reset pulse. Transient immunity can be improved by adding a capacitor in close proximity to the V CC pin of the MAX809.Figure 2.

This means CMOS logic inputs to the µP will be floating at an undetermined voltage. Most digital systems are completely shutdown well above this voltage.However, in situations where RESET must be maintainedvalid to V CC = 0 V , a pull–down resistor must be connected from RESET to ground to discharge stray capacitances and hold the output low (Figure 3). This resistor value, though not critical, should be chosen such that it does not appreciably load RESET under normal operation (100 k W will be suitable for most applications).Figure 3. Ensuring RESET Valid to V CC = 0 VProcessors With Bidirectional I/O PinsSome µP’s (such as Motorola 68HC11) have bi–directional reset pins. Depending on the current drive capability of the processor pin, an indeterminate logic level may result if there is a logic conflict. This can be avoided by adding a 4.7 k W resistor in series with the output of the MAX809 (Figure 4). If there are other components in the system which require a reset signal, they should be buffered so as not to load the reset line. If the other components are required to follow the reset I/O of the µP, the buffer should be connected as shown with the solid line.Figure 4.

The auxiliary supply of the generator must also meet the following conditions:∙Vac peak voltage: below 410V.∙Vac frequency: 50Hz.∙RMS voltage of the AC waveform: 230Vac ± 10%.It is important to check these conditions because many engine driven generators produce high voltage spikes. Operation of this machine on engine driven generators not conforming to these conditions is not recommended and may damage the machine.Output ConnectionsWARNINGUse ONLY the torch supplied with this machine. For areplacement refer to the Maintenance section of this manual.WARNINGAlways turn OFF the machine when working on the torch.WARNINGDo not remove the work clamp during cutting, plasma cutting generates high voltages that can kill.WARNINGOpen Circuit Voltage U0 > 100VDC. For more information refer to the Technical Specification section. This machine is sent from the factory with a cutting torch and work clamp installed. The work clamp must be securely connected to the work piece. If the work piece is painted or extremely dirty it may be necessary to expose the bare metal in order to make a good electrical connection.Built-In CompressorThis machine has a built-in compressor that allow to operates in areas where an external primary air is not available. Only an electrical mains supply is necessary!Controls and Operational Features CITOCUT 25i front command panel.Commands descriptions:A. Output Current Knob: Potentiometer used to set theoutput current used during cutting. Refer to the Technical Specification section for more information about the machine rated current range.Air Purge: The Output Current Knob completely rotated counterclockwise enables the air purge function. A 5 minutes timeout stops the purge function; this happens only if the Output Current Knob remains in the purge mode for a long time.B. Power ON/OFF green LED: It lights up when themachine is ON.C. Output red LED: See meanings in the following table.D. Thermal yellow LED: See meanings in the followingtable.LEDs MeaningOutput(Red)Thermal(Yellow)On Off The cutting torch is energized.On OnPart in place error: the retaining capis not properly screwed.To restore the machine:∙Screw firmly the torch retainingcap.∙Wait for 5seconds; during thistime the Output and ThermalLEDs blinks alternately.∙After 5seconds the machine isautomatically restored and readyto operate.Off OnThe machine is overheated and theoutput has been disabled. Thisusually occurs when the duty cycleof the machine has been exceeded.Leave the machine On to allow theinternal components to cool. Whenthe thermal LED turns off, normaloperation is again possible.Off BlinkMains undervoltage or overvoltageerror: the machine is disabled.When the mains return in thecorrect range, the machine restartautomatically.Blink Off Low air pressure error.To check / adjust the air pressure(see recommended values in theTecnical Specifications of thismanual):∙Put the machine in Purge mode[A].∙ Check and adjust the airpressure through themanometer and air pressureregulator knob [F].∙If necessary, check and adjustalso the inlet air pressurethrough the commands of theexternal compressor.E. Internal / External air selection :This switch determine the air supply. With the “InCompr” position selected, the machine operatesthrough the built-in compressor. With the “Ext Air”position selected, the internal compressor iscompletely disabled and the machine operatesthrough an external air supply hose connected to theproper air inlet connection placed on the machine rearside.WARNINGIf operate with external air, be sure to select the “Ext Air” switch position in order to completely disable the built-in compressor. Otherwise the compressor may be damagedby the probable greater pressure of the external air.F. Air Pressure Gauge and Regulator Knob :Allow to regulate and monitoring the air pressure.G. Fan: Provides machine cooling. It is switched ONwith the machine and continues to run till the machine is turned OFF.H. Power Switch: It turns ON / OFF the input power tothe machine.I. Input cable: Connect it to the mains.J. Air Inlet : If the “Ext Air” operating mode is selected, connect here the hose carrying the air to the machine.WARNINGA clean, dry air must be supplied to the machine. A pressure setting above 7.5bar could damage the torch. Failure to observe these precautions could result in excessive operating temperatures or damage to the torch. Cutting ProcessThe air plasma cutting process uses air as primary cutting gas and as torch cooling gas.The air is provided by the built-in compressor with a pressure of 3.5bar (approximate value).The Citicut 25i can reach the best cutting performances operates also with external air; in this case the air pressure is limited by a pressure regulator [F], set at factory at 5.0bar. In case to adjust the air pressure, put the machine in Purge mode [A].The pilot arc is struck as follow:∙“In Compr” operating mode:The torch button enables the built-in compressorthat provide the air flow to the torch. Releasing thetorch button the cutting process is stopped, but thecompressor continues to run for the post-flowstage.∙“Ext Air” operating mode: the torch button energize an electrovalve (solenoid valve). Thisvalve lets the air flow during the cutting and thepost-flow stages.The design concept at the basis of these power sources is to have available a current which remains constant at the set value, independently from the length of the plasma arc. When preparing to cut, make sure you have all materials needed to complete the job and have taken all safety precautions. Install the machine as instructed in this manual and remember to attach the work clamp to the work piece.∙Turn ON the Power Switch [H] placed on the back of the machine; the LED [B] on the front panel will turn ON. The unit is now ready to operate.∙Check that the primary air is available through the Air Purge function [A].∙Set the desired current value with the Output Current[A] knob.To start the cutting process just press the torch button, making sure you are not aiming the torch air blow towards people or foreign objects. During the cutting process it is possible to hold the torch away from the work piece for an extended period of time.To piercing the work piece, lower thetorch onto the metal at a 30° angleaway from the operator. This will blowthe dross (melted metal) away fromthe torch tip.Slowly rotate the torch to the verticalposition as the arc becomes deeper.Once the work piece is pierced normalcutting can occur.Keep moving while cuttingand cut at a steady speed sothat the arc leg is 10° to 20°behind the travel direction.Use a 5° to 15° leading anglein the direction of the cut.Once the cutting process isterminated releasing off thetorch button will cause theplasma arc to be turned off;the air flow will continue forapproximately 20sec. (post-flow) to allow the cooling down of the torch.MaintenanceWARNINGFor any maintenance or repair operations it is recommended to contact the nearest technical service center or Lincoln Electric. Maintenance or repairs performed by unauthorized service centers or personnel will null and void the manufacturers warranty.The frequency of the maintenance operations may vary in accordance with the working environment. Any noticeable damage should be reported immediately.∙Check cables and connections integrity. Replace, if necessary.∙Regularly clean the torch head, check its consumables and if necessary replace them.WARNINGRefer to the torch instructions before changing or servicing the torch.∙Keep clean the machine. Use a soft dry cloth to clean the enclosing case, especially the airflow inlet / outlet louvers.∙Regularly clean the compressor air inlet filter.WARNINGDo not open this machine and do not introduce anything into its openings. Power supply must be disconnected from the machine before maintenance and service. After each repair, perform proper tests to check safety requirements.Cutting SpeedThe cutting speed is a function of:∙ Thickness and of material to be cut.∙ Value of set current. The current setting affects thequality of the cut edge.∙ Geometrical shape of the cut (whether straight orcurved). In order to provide indications on the most suitable setting, the following table was established, based on tests performed on an automatic test-bench; the best results however can only be achieved from direct experience by the operator in his actual working conditions.CITOCUT 25i (internal air) CITOCUT 25i (external air) Speed (cm/min.)Speed (cm/min.)T h i c k n e s sC u r r e n t (A )M I L D S T E E LA L U M I N U MS T A I N L E S S S T E E LC u r r e n t (A )M I L D S T E E L A L U M I N U M S T A I N L E S S S T E E L 4 mm 25 147 94 77.7 25 179 122 112.8 5 mm 25 108 86 59 25 131 104 90 6 mm 25 73 68 47 25 80.6 81.6 70 ¼” 25 55 58 43 25 67 70 62 8 mm --- --- --- --- --- --- --- --- ⅜” 25 10 --- 23 25 12 --- 3010 mm 25 --- --- 20.4 25 --- --- 23.6 11 mm --- --- --- --- --- --- --- --- ½” 25 --- --- 11 25 --- --- 12 15 mm------------------------ ¾” --- --- --- --- --- --- --- ---Customer Assistance PolicyThe business of The Lincoln Electric Company is manufacturing and selling high quality welding equipment, consumables, and cutting equipment.

General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

General Description The MAX803/MAX809/MAX810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external compo-nents and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V-powered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after V CC has risen above the reset thresh-old. Reset thresholds suitable for operation with a vari-ety of supply voltages are available.The MAX803 has an open-drain output stage, while the MAX809/MAX810 have push-pull outputs. The MAX803’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than V CC. The MAX803/MAX809 have an active-low RESET output, while the MAX810 has an active-high RESET output. The reset comparator is designed to ignore fast transients on V CC, and the outputs are guaranteed to be in the correct logic state for V CC down to 1V.Low supply current makes the MAX803/MAX809/ MAX810 ideal for use in portable equipment. The MAX803 is available in a 3-pin SC70 package, and the MAX809/MAX810 are available in 3-pin SC70 or SOT23 packages.Applications ComputersControllersIntelligent InstrumentsCritical µP and µC Power MonitoringPortable/Battery-Powered EquipmentAutomotive ____________________________Features o Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltageso Fully Specified Over Temperatureo Available in Three Output ConfigurationsOpen-Drain RESET Output (MAX803)Push-Pull RESET Output (MAX809)Push-Pull RESET Output (MAX810)o140ms min Power-On Reset Pulse Widtho12µA Supply Currento Guaranteed Reset Valid to V CC= +1Vo Power Supply Transient Immunityo No External Components o3-Pin SC70 and SOT23 Packages MAX803L/M/R/S/T/Z, MAX809J/L/M/R/S/T/Z, MAX810L/M/R/S/T/Z3-Pin Microprocessor Reset Circuits________________________________________________________________Maxim Integrated Products1Pin Configuration Typical Operating Circuit19-0344; Rev 4; 12/99Note: These parts are offered in 2.5k or 10k reels, and must beordered in 2.5k or 10k increments.

The MAX803/MAX809/MAX810 assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after V CC has risen above the reset thresh-old. The MAX803 uses an open-drain output, and the MAX809/MAX810 have a push-pull output stage.Connect a pull-up resistor on the MAX803’s RESET out-put to any supply between 0 and 6V.Applications InformationNegative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, the MAX803/MAX809/MAX810 are relatively immune to short-duration negative-going V CC transients (glitches).Figure 1 shows typical transient duration vs. reset com-parator overdrive, for which the MAX803/MAX809/MAX810 do not generate a reset pulse. The graph was generated using a negative-going pulse applied to V CC ,starting 0.5V above the actual reset threshold and end-ing below it by the magnitude indicated (reset compara-tor overdrive). The graph indicates the maximum pulse width a negative-going V CC transient can have without causing a reset pulse. As the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, for the MAX8__L and MAX8__M, a V CC transient that goes 100mV below the reset threshold and lasts 20µs or less will not cause a reset pulse. A 0.1µF bypass capacitor mounted as close as possible to the V CC pin provides additional transient immunity.Ensuring a Valid Reset OutputDown to V CC = 0When V CC falls below 1V, the MAX809 RESET output no longer sinks current—it becomes an open circuit.Therefore, high-impedance CMOS logic inputs con-nected to RESET can drift to undetermined voltages.This presents no problem in most applications since most µP and other circuitry is inoperative with V CC below 1V. However, in applications where RESET must be valid down to 0V, adding a pull-down resistor to RESET causes any stray leakage currents to flow to3-Pin Microprocessor Reset CircuitsFigure 2.

R1’s value is not critical; 100k Ωis large enough not to load RESET and small enough to pull RESET to ground.A 100k Ωpull-up resistor to V CC is also recommended for the MAX810 if RESET is required to remain valid for V CC < 1V.Interfacing to µPs with Bidirectional Reset PinsSince the RESET output on the MAX803 is open drain,this device interfaces easily with µPs that have bidirec-tional reset pins, such as the Motorola 68HC11.Connecting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 3).MAX803 Open-Drain RESET Output Allows Use with Multiple SuppliesG enerally, the pull-up connected to the MAX803 will connect to the supply voltage that is being monitored at the IC’s V CC pin. However, some systems may use the open-drain output to level-shift from the monitored sup-ply to reset circuitry powered by some other supply (Figure 4). Note that as the MAX803’s V CC decreases below 1V, so does the IC’s ability to sink current at RESET . Also, with any pull-up, RESET will be pulled high as V CC decays toward 0. The voltage where this occurs depends on the pull-up resistor value and the voltage to which it is connected.Benefits of Highly AccurateReset ThresholdMost µP supervisor ICs have reset threshold voltages between 5% and 10% below the value of nominal sup-ply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the sup-ply is 10% below nominal.When using ICs rated at only the nominal supply ±5%,this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted.The MAX8__L/T/Z use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal.3-Pin Microprocessor Reset Circuits 6_______________________________________________________________________________________Figure 4.

Each section is described in detail.+5V to ±10V Dual Charge-Pump Voltage Converter The +5V to ±10V conversion is performed by two charge-pump voltage converters (Figure 4). The first uses capaci-tor C1 to double +5V to +10V, storing +10V on the V+output filter capacitor, C3. The second chargepump volt-age converter uses capacitor C2 to invert +10V to -10V,storing -10V on the V- output filter capacitor, C4.The MAX201 and MAX209 include only the V+ to Vcharge pump, and are intended for applications that have a V CC = +5V supply and a V+ supply in the +9V to +13.2V range.In shutdown mode, V+ is internally connected to V CC by a 1kΩ pulldown resistor and V- is internally connected to ground by a 1kΩ pullup resistor.RS-232 Drivers When V CC = +5V, the typical driver output-voltage swing is ±8V when loaded with a nominal 5kΩ RS-232 receiver. The output swing is guaranteed to meet the EIA/TIA-232E and V.28 specifications, which call for ±5V minimum out-put levels under worst-case conditions. These include a minimum 3kΩ load, V CC = +4.5V, and the maximum operating temperature. The open-circuit output-voltage swing ranges from (V+ - 0.6V) to V-.Input thresholds are both CMOS and TTL compatible. The inputs of unused drivers can be left unconnected since 400kΩ pullup resistors to V CC are included onchip. Since all drivers invert, the pullup resistors force the outputs of unused drivers low. The input pullup resistors typically source 15μA; therefore, the driver inputs should be driven high or open circuited to minimize power-supply current in shutdown mode.When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1mA, even if the transmitter output is backdriven between 0V and (V CC + 6V). Below -0.5V, the transmitter output is diode clamped to ground with a 1kΩ series impedance. The transmitter output is also zener clamped to approxi-mately (V CC + 6V), with a 1kΩ series impedance.Figure 1. Shutdown Current Test CircuitFigure 2.

MAX471/MAX472的特点、功能美国美信公司生产的精密高端电流检测放大器是一个系列化产品，有MAX471/MAX472、MAX4172/MAX4173等。

它们均有一个电流输出端，可以用一个电阻来简单地实现以地为参考点的电流/电压的转换，并可工作在较宽电压内。

MAX471/MAX472具有如下特点：●具有完美的高端电流检测功能；●内含精密的内部检测电阻（MAX471）；●在工作温度范围内，其精度为2%；●具有双向检测指示，可监控充电和放电状态；●内部检测电阻和检测能力为3A，并联使用时还可扩大检测电流范围；●使用外部检测电阻可任意扩展检测电流范围（MAX472）；●最大电源电流为100μA；●关闭方式时的电流仅为5μA；●电压范围为3～36V；●采用8脚DIP/SO/STO三种封装形式。

MAX471/MAX472的引脚排列如图1所示，图2所示为其内部功能框图。

表1为MAX471/MAX472的引脚功能说明。

MAX471的电流增益比已预设为500μA/A，由于2kΩ的输出电阻（ROUT）可产生1V/A的转换，因此±3A时的满度值为3V.用不同的ROUT电阻可设置不同的满度电压。

但对于MAX471，其输出电压不应大于VRS+。

对于MAX472，则不能大于。

MAX471引脚图如图１所示，MAX472引脚图如图２所示。

ADJUSTMENT3.1 Voltage adjustmentThe generator output voltage can be altered by adjustment of the volt VR on the AVR board, or by the external trimmer (1K Ω) if fitted.1. The terminals 1&2 must be linked if no hand trimmer.2. Before start the generator, please turn the Volt trimmer on the AVR board fully anticlockwise Turn the external trimmer to midway position.3. Turn the stability trimmer on the AVR board to midway position.4. Connect a voltmeter to generator output voltage terminals.5. Start generator set and run on no load at nominal frequency 50 ~ 53Hz or 60~63Hz.6. If the red Led is illuminated, refer to the under frequency roll off adjustment.7. Carefully turn volt trimmer clockwise until rated voltage is reached.______________________________________________________________________________________EA440-T33.2 Stability adjustmentIf a replacement AVR has been fitted or re-setting of the stability control is required, turn the stability trimmer slowly clockwise until the output voltage is steady, on or off load.3.3 Droop adjustmentGenerator intended for parallel are fitted with a quadrature droop CT with provides a power factor dependent signal for the AVR. The CT is connected to S1,S2 on the AVR. The Droop adjustment is normally present in the works to give 5% voltage droop at full load zero power factor. Clockwise increases the amount of CT signal injected into the AVR and increases the droop with lagging power factor. With the control fully anticlockwise there is no droop.3.4 Trim adjustmentAn auxiliary input is provided to connect to A1, A2. It is designed to accept DC ± 5V.Turn the TRIM trimmer fully anticlockwise has no effect, Clockwise it has maximum effect.Outline DrawingFigure 1Wiring DrawingFigure 3______________________________________________________________________________________ 4EA440-T4.
