These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V, and 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 100ms after V CC has risen above the reset threshold.The only difference between the devices is their output.The MAX6326/MAX6346 (push-pull) and MAX6328/MAX6348 (open-drain) have an active-low reset output.The MAX6327/MAX6347 have an active-high push-pull reset output. All of these parts are guaranteed to be in the correct state for V CC down to 1V. The reset compara-tor is designed to ignore fast transients on V CC . Reset thresholds are factory-trimmable between 2.2V and 4.63V, in approximately 100mV increments. Twenty-one standard versions are available. Contact the factory for availability of nonstandard versions.Ultra-low supply currents (1µA max for the MAX6326/MAX6327/MAX6328) make these parts ideal for use in portable equipment. All six devices are available in space-saving SOT23 and SC70 packages.ApplicationsComputers Intelligent Instruments Controllers AutomotiveCritical µP and µC Portable/Battery-Powered Power MonitoringEquipmentFeatureso Ultra-Low 1µA (max) Supply Current (MAX6326/MAX6327/MAX6328)o Precision Monitoring of 2.5V, 3V, 3.3V, and 5V Power-Supply Voltageso Reset Thresholds Available from 2.2V to 4.63V o Fully Specified Over Temperatureo 100ms (min) Power-On Reset Pulse Width o Low Costo Available in Three Versions: Push-Pull RESET ,Push-Pull RESET, and Open-Drain RESET o Power-Supply Transient Immunity o No External Componentso 3-Pin SC70/SOT23 Packageso Pin Compatible with MAX803/MAX809/MAX810MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX63483-Pin, Ultra-Low-Power SC70/SOTµP Reset Circuits________________________________________________________________Maxim Integrated Products 1Pin Configuration19-1294; Rev 3; 1/00†The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348 are available in factory-set V CC reset thresholds from 2.2V to 4.63V, in approximately 0.1V increments.

Connecting the µP supervisor’s RESET output directly to the microcon-troller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 1).Negative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going V CC transients (glitches).The Typical Operating Characteristics show the Maxi-mum Transient Duration vs. Reset Threshold Overdrive graph, for which reset pulses are not generated. The graph shows the maximum pulse width that a negative-going V CC transient may typically have when issuing a reset signal. As the amplitude of the transient increas-es, the maximum allowable pulse width decreases.Figure 1. Interfacing to µPs with Bidirectional Reset PinsTable 1.

Run the ground connection from the ground screw to the grounding surface prior to connectingdevices.Wiring the Power InputsThe IKS series supports dual redundant power supplies, named “Power Supply 1 (PWR1)” and “Power Supply 2 (PWR2)”. Theconnections for PWR1 and PWR2 are located on the terminal block. Front view of the terminal block connectors are shown here.– 4 –– 5 –– 6 –/supportThe Americas: +1-714-528-6777 (toll-free: 1-888-669-2872)Europe: +49-89-3 70 03 99-0 Asia-Pacific: +886-2-8919-1230China: +86-21-5258-9955 (toll-free: 800-820-5036)2013 Moxa Inc. All rights reserved.Wiring the Redundant Power InputsThe IKS-6324 switch has two sets of power input—power input 1 and power input 2.STEP 1: Insert the dual set positive/negative DC wires into PWR1and PWR2 terminals (+ → pins 1, 9, - → pins 2, 10). Or insert the L/N AC wires into the PWR1 terminals (L → pin 1, N → pin 2). STEP 2: To keep the DC or AC wires from pulling loose, use ascrewdriver to tighten the wire-clamp screws on the front of the terminal block connector.LED IndicatorsThe front panel of the IKS-6324 switch contains several LED indicators. The function of each LED is described in the table below.NOTE: Use the Mode push-button switch to cycle among the LNK/ACT, SPEED, and FDX/HDX LEDs. The status of these three settings is indicated by the LEDs for the various ports. The system will switch to LNK/ACT automatically after 5 seconds.* Slot 1 (M1) is mainly used for Gigabit modules. If 100BaseFX modules are used in Slot 1 (M1), the modules will not support “Far End Fault”. The Link/ACT LED indicator will stay at “Green (ON)” status when Fiber TX cable is unplugged.SpecificationsTechnology Standards IEEE802.3, 802.3u, 802.3ab, 802.3z, 802.3x Flow Control IEEE802.3x flow control, back pressure flow controlInterface Fast Ethernet 10/100BaseT(X) or 100BaseFX (SC/ST connector)Gigabit Ethernet10/100/1000BaseT(X),1000BaseSX/LX/LHX/ZX (SFP slot, LC connector)System LED Indicators STAT, PWR1, PWR2, FAULTModule LED IndicatorsLNK/ACT, FDX/HDX, SPEED Optical Fiber (100BaseFX) Distance Multi mode0 to 5 km, 1300 nm (50/125μm , 800 MHz*km) 0 to 4 km, 1300 nm (62.5/125μm , 500 MHz*km)Single mode0 to 40 km, 1310 nm (9/125μm , 3.5 PS/(nm*km))Min.

General DescriptionThe MAX9030/MAX9031/MAX9032/MAX9034 single/dual/quad comparators are optimized for single-supply applications from +2.5V to +5.5V but can also be oper-ated from dual supplies. These comparators have a 188ns propagation delay and consume 35µA of supply current per comparator over the -40°C to +125°C oper-ating temperature range. The combination of low-power, single-supply operation down to +2.5V, and ultra-small footprint makes these devices ideal for portable applications.The MAX9030 is a low-cost single comparator with shutdown. The MAX9031, MAX9032, and MAX9034 are low-cost single, dual, and quad comparators without shutdown, respectively. The comparators’ 4mV of built-in hysteresis provides noise immunity and prevents oscillations even with a slow-moving input signal. The input common-mode range extends from the negative supply to within 1.1V of the positive supply. The design of the comparator output stage substantially reduces switching current during output transitions, virtually eliminating power-supply glitches.The MAX9030 single comparator with shutdown is avail-able in the space-saving 6-pin SC70 and SOT23 pack-ages. The MAX9031 single comparator is available in tiny 5-pin SC70 and SOT23 packages. The MAX9032 dual comparator is available in 8-pin SOT23 and µMAX pack-ages, and the MAX9034 quad comparator is available in a 14-pin TSSOP package.________________________ApplicationsFeatureso Low-Cost Solution Available in Space-Saving SC70 Packages (MAX9030/MAX9031)o +2.5 to +5.5V Single-Supply Voltage Range o Comparator Output Swings Rail-to-Rail ®o Internal 4mV Comparator Hysteresis o 188ns Propagation Delay o Low 35µA Supply Currento No Phase Reversal for Overdriven Inputs o Space-Saving Packages5-Pin SC70 (MAX9031)6-Pin SC70 (MAX9030)8-Pin SOT23 (MAX9032)14-Pin TSSOP (MAX9034)MAX9030/MAX9031/MAX9032/MAX9034Low-Cost, Ultra-Small, Single/Dual/QuadSingle-Supply Comparators________________________________________________________________Maxim Integrated Products1Pin Configurations19-1767; Rev 0; 10/00Ordering Information*Future product–contact factory for availability.Battery-PoweredPortable SystemsMobile Communications Sensor Signal Detection Photodiode PreampsDigital Line Receivers Keyless Entry Systems Threshold Detectors/DiscriminatorsTypical Application Circuit appears at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.For price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642,or visit Maxim’s website at .M A X 9030/M A X 9031/M A X 9032/M A X 9034Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V DD = +5V, V SS = 0, V CM = 0, V SHDN = +5V (Note 1), T A = -40°C to +125°C, unless otherwise noted.

They have an operating supply voltage from +2.5V to +5.5V when operating from a single supply and from ±1.25V to ±2.75V when operating from dual power supplies, and consume only 35µA. Their common-mode input voltage range extends from the negative supply to within 1.1V of the positive supply. Internal hysteresis ensures clean output switching, even with slow-moving input signals.Shutdown ModeThe MAX9030 comparator comes with a power-saving shutdown mode. When in shutdown, the supply current drops from a typical 35µA to 0.05µA, and the outputs become high impedance. SHDN has a high input imped-ance and typically draws 0.1µA when connected to V SS or V DD . A maximum logic low voltage of 0.3V ✕ V DDapplied to SHDN places the device in the shutdown mode. A minimum logic high voltage of 0.7V ✕ V DD applied to SHDN will enable normal operation. To dis-able shutdown, connect SHDN to V DD .Applications InformationAdding HysteresisH ysteresis extends the comparator ’s noise margin by increasing the upper threshold and decreasing the lower threshold. A voltage-divider from the output of the comparator sets the trip voltage. Therefore, the trip volt-age is related to the output voltage.These comparators have 4mV internal hysteresis.Additional hysteresis can be generated with two resis-tors using positive feedback (Figure 1). Use the follow-ing procedure to calculate resistor values:Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators 6_______________________________________________________________________________________Pin Description1) Find the trip points of the comparator using these formulas:V TH = V REF +[((V DD - V REF )R2) / (R1 + R2)V TL = V REF (1 - (R2 / (R1 + R2))]where V TH is the threshold voltage at which the com-parator switches its output from high to low as V IN rises above the trip point. V TL is the threshold volt-age at which the comparator switches its output from low to high as V IN drops below the trip point.2) The hysteresis band will be:V HYS = V TH - V TL = V DD (R2 / (R1 + R2))3) In this example, let V DD = +5V and V REF = +2.5V.V TH = 2.5V + 2.5(R2 / (R1 + R2))VandV TL = 2.5[1 - (R2 / (R1 + R2))]4) Select R2. In this example, we will choose 1k Ω.5) Select V HYS . In this example, we will choose 50mV.6) Solve for R1.V HYS = V DD (R2 / (R1 + R2))0.050V = 5(1000Ω/(R1 + 1000Ω)) Vwhere R1 ≈100k Ω, V TH = 2.525V, and V TL = 2.475V.The above-described design procedure assumes rail-to-rail output swing. If the output is significantly loaded,the results should be corrected.Board Layout and BypassingUse 100nF bypass as a starting point. Minimize signal trace lengths to reduce stray capacitance. Minimize the capacitive coupling between IN- and OUT. For slow-moving input signals (rise-time > 1ms), use a 1nF capacitor between IN+ and IN-.Biasing for Data RecoveryDigital data is often embedded into a bandwidth and amplitude-limited analog path. Recovering the data can be difficult. Figure 2 compares the input signal to a time-averaged version of itself. This self-biases the threshold to the average input voltage for optimal noise margin. Even severe phase distortion is eliminated from the digital output signal. Be sure to choose R1 and C1so that:ƒCAR >> 1 / (2πR1C1)where ƒCAR is the fundamental carrier frequency of the digital data stream.MAX9030/MAX9031/MAX9032/MAX9034Low-Cost, Ultra-Small, Single/Dual/QuadSingle-Supply Comparators_______________________________________________________________________________________7M A X 9030/M A X 9031/M A X 9032/M A X 9034Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators 8_______________________________________________________________________________________Typical Application CircuitChip InformationTRANSISTOR COUNT/MAX9030/MAX9031: 123TRANSISTOR COUNT/MAX9032: 184TRANSISTOR COUNT/MAX9034: 368MAX9030/MAX9031/MAX9032/MAX9034Low-Cost, Ultra-Small, Single/Dual/QuadSingle-Supply ComparatorsPackage InformationM A X 9030/M A X 9031/M A X 9032/M A X 9034Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators 10______________________________________________________________________________________Package Information (continued)MAX9030/MAX9031/MAX9032/MAX9034Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply ComparatorsPackage Information (continued)Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
