________________General DescriptionThe MAX3222/MAX3232/MAX3237/MAX3241 trans-ceivers have a proprietary low-dropout transmitter out-put stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The devices require only four small 0.1µF external charge-pump capacitors. The MAX3222, MAX3232, and MAX3241 are guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The MAX3237 is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232output levels.The MAX3222/MAX3232 have 2 receivers and 2 drivers. The MAX3222 features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply cur-rent. The MAX3222 and MAX3232 are pin, package,and functionally compatible with the industry-standard MAX242 and MAX232, respectively.The MAX3241 is a complete serial port (3 drivers/5 receivers) designed for notebook and subnotebook computers. The MAX3237 (5 drivers/3 receivers) is ideal for fast modem applications. Both these devices feature a shutdown mode in which all receivers can remain active while using only 1µA supply current. Receivers R1(MAX3237/MAX3241) and R2 (MAX3241) have extra out-puts in addition to their standard outputs. These extra outputs are always active, allowing external devices such as a modem to be monitored without forward bias-ing the protection diodes in circuitry that may have V CC completely removed.The MAX3222, MAX3237, and MAX3241 are available in space-saving TSSOP and SSOP packages.________________________ApplicationsNotebook, Subnotebook, and Palmtop Computers High-Speed ModemsHand-Held Equipment Peripherals Printers3.0V to 5.5V , Low-Power , up to 1Mbps, T rue RS-232Transceivers Using Four 0.1µF External CapacitorsMegaBaud and UCSP are trademarks of Maxim Integrated Products, Inc.Typical Operating Circuits appear at end of data sheet.MAX3222/MAX3232/ MAX3237/MAX3241捷多邦，您值得信赖的PCB打样专家！3.0V to 5.5V , Low-Power , up to 1Mbps, T rue RS-232Transceivers Using Four 0.1µF External CapacitorsABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +3.0V to +5.5V, C1–C4 = 0.1µF (Note 2), T A = T MIN to T MAX , unless otherwise noted.

The charge pumps operate in a discontinuous mode; if the output voltages are less than 5.5V, the charge pumps are enabled, and if the output voltages exceed 5.5V, the charge pumps are disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies.RS-232 TransmittersThe transmitters are inverting level translators that con-vert CMOS-logic levels to 5.0V EIA/TIA-232 levels.The MAX3222/MAX3232/MAX3241 transmitters guaran-tee a 120kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF, providing compatibility with PC-to-PC communication software (such as LapLink™).Typically, these three devices can operate at data rates of 235kbps. Transmitters can be paralleled to drive multi-ple receivers or mice.The MAX3222/MAX3237/MAX3241’s output stage is turned off (high impedance) when the device is in shut-down mode. When the power is off, the MAX3222/MAX3232/MAX3237/MAX3241 permit the outputs to be driven up to ±12V.The transmitter inputs do not have pullup resistors.Connect unused inputs to GND or V CC .MAX3237 MegaBaud OperationIn normal operating mode (MBAUD = GND ), the MAX3237 transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF.This provides compatibility with PC-to-PC communica-tion software, such as Laplink.For higher speed serial communications, the MAX3237features MegaBaud operation. In MegaBaud operating mode (MBAUD = V CC ), the MAX3237 transmitters guar-antee a 1Mbps data rate with worst-case loads of 3k Ωin parallel with 250pF for 3.0V < V CC < 4.5V. For 5V ±10%operation, the MAX3237 transmitters guarantee a 1Mbps data rate into worst-case loads of 3k Ωin parallel with 1000pF.Figure 1.

The MAX3222/MAX3237/MAX3241 receivers have inverting three-state outputs. In shutdown, the receivers can be active or inactive (Table 1).The complementary outputs on the MAX3237 (R1OUTB)and the MAX3241 (R1OUTB, R2OUTB) are always active,regardless of the state of EN or SHDN . This allows for Ring Indicator applications without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC is set to 0V in shutdown to accommodate peripherals, such as UARTs (Figure 2).MAX3222/MAX3237/MAX3241Shutdown ModeSupply current falls to less than 1µA in shutdown mode (SHDN = low). When shut down, the device’s charge pumps are turned off, V+ is pulled down to V CC , V- is pulled to ground, and the transmitter outputs are dis-abled (high impedance). The time required to exit shut-down is typically 100µs, as shown in Figure 3. Connect SHDN to V CC if the shutdown mode is not used. SHDN has no effect on R_OUT or R_OUTB.MAX3222/MAX3237/MAX3241Enable ControlThe inverting receiver outputs (R_OUT) are put into a high-impedance state when EN is high. The complemen-tary outputs R1OUTB and R2OUTB are always active,regardless of the state of EN and SHDN (Table 1). EN has no effect on T_OUT.__________Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; polarized or nonpolarized capacitors can be used. The charge pump requires 0.1µF capaci-tors for 3.3V operation. For other supply voltages, refer to Table 2 for required capacitor values. Do not use values lower than those listed in Table 2. Increasing the capaci-tor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consump-tion. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1 without also increasing the values of C2, C3, and C4, to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade exces-sively with temperature. If in doubt, use capacitors with a higher nominal value. The capacitor’s equivalent series resistance (ESR), which usually rises at low tempera-tures, influences the amount of ripple on V+ and V-.Figure 2.

In applications that are sensitive to power-supply noise, decouple V CC to ground with a capacitor of the same value as charge-pump capacitor C1. Connect bypass capacitors as close to the IC as possible.Operation Down to 2.7VTransmitter outputs will meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V.Transmitter Outputs whenExiting ShutdownFigure 3 shows two transmitter outputs when exiting shutdown mode. As they become active, the two trans-mitter outputs are shown going to opposite RS-232 lev-els (one transmitter input is high, the other is low).Each transmitter is loaded with 3k Ωin parallel with 2500pF. The transmitter outputs display no ringing or undesirable transients as they come out of shutdown.Note that the transmitters are enabled only when the magnitude of V- exceeds approximately 3V.Mouse DriveabilityThe MAX3241 has been specifically designed to power serial mice while operating from low-voltage power sup-plies. It has been tested with leading mouse brands from manufacturers such as Microsoft and Logitech.

三极管知识简介概述半导体三极管也称为晶体三极管，可以说它是电子电路中最重要的器件。

它最主要的功能是电流放大和开关作用。

三极管顾名思义具有三个电极。

二极管是由一个PN结构成的，而三极管由两个PN结构成，共用的一个电极成为三极管的基极(用字母b表示)。

其他的两个电极成为集电极(用字母c表示)和发射极(用字母e表示)。

由于不同的组合方式，形成了一种是NPN型的三极管，另一种是PNP型的三极管。

三极管的种类很多，并且不同型号各有不同的用途。

三极管大都是塑料封装或金属封装，常见三极管的外观，有一个箭头的电极是发射极，箭头朝外的是NPN型三极管，而箭头朝内的是PNP型。

实际上箭头所指的方向是电流的方向。

电子制作中常用的三极管有90××系列，包括低频小功率硅管9013(NPN)、9012(PNP)，低噪声管9014(NPN)，高频小功率管9018(NPN)等。

它们的型号一般都标在塑壳上，而样子都一样，都是TO-92标准封装。

在老式的电子产品中还能见到3DG6(低频小功率硅管)、3AX31(低频小功率锗管)等，它们的型号也都印在金属的外壳上。

我国生产的晶体管有一套命名规则，电子工程技术人员和电子爱好者应该了解三极管符号的含义。

符号的第一部分“3”表示三极管。

符号的第二部分表示器件的材料和结构：A——PNP型锗材料；B——NPN型锗材料；C——PNP型硅材料；D——NPN型硅材料。

符号的第三部分表示功能：U——光电管；K——开关管；X——低频小功率管；G——高频小功率管；D——低频大功率管；A——高频大功率管。

另外，3DJ型为场效应管，BT打头的表示半导体特殊元件。

三极管最基本的作用是放大作用，它可以把微弱的电信号变成一定强度的信号，当然这种转换仍然遵循能量守恒，它只是把电源的能量转换成信号的能量罢了。

三极管有一个重要参数就是电流放大系数 b。

当三极管的基极上加一个微小的电流时，在集电极上可以得到一个是注入电流b 倍的电流，即集电极电流。

Quad SP6330-SP6332- SP6334 Quad Power Supervisory Circuit Family is a family of microprocessor reset supervisory circuits with multiple reset voltages. The family provides low voltage monitoring ability for up-to four supplies with two precision factory-set thresholds and two user defined custom thresholds. These circuits perform a single function: if any of the input supply voltages drops below its associated threshold, reset outputs are asserted. The SP6330, SP6332, and SP6334 are packaged in an 8-pin TSOT package. All devices are fully specified over -40o C to +85o C temperature range.50ms, 100ms, 200ms and 400ms ■ Watch Dog Input Functionality -- WDI ■ Manual Reset Input (Active Low) -- MRIB ■ 8 Pin TSOT packageDESCRIPTIONAvailable in Lead Free PackagingAVAILABLE PINOUTSTYPICAL APPLICATION CIRCUITTerminal Voltage (with respect to GND)V1, V2..................................................... -0.3 to +6V Open-Drain RSTB .......................................-0.3 to +6V CMOS RST, RSTB, ..................... -0.3 to (V1+0.3V) Input Current/OutputCurrent..................................,,........................20mA V3, V4, MRIB, WDI ........................-0.3 to (V1+0.3V)ABSOLUTE MAXIMUM RATINGSOperating TemperatureRange ...............................................-40°C to +85 °C Storage TemperatureRange...............................................-65°C to 150°C Thermal Resistance O JA .............................134°C/WThese are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.

The family is designed to supervise up to 4 independent supply voltages. V1 and V2 supply inputs have their resistor dividers on the chip. Their trip thresholds are factory trimmed. V3 and V4 inputs allow user to customizeBlock Diagramtwo additional supply thresholds to be monitored by means of external resistor dividers. The devices also feature manual reset and watchdog functionalities.As these devices do not have watchdog outputs, the watchdog timer is serviced internally during the watchdog timeout period when WDI is left unconnected. The watchdog functionality can be disabled by leaving the WDI input floating.RSTB (RST)GND MRIBFigure 1: Functionality of a SP63XX family member with manual reset and watchdog capabilities but without WDOB output.• V1 > Vth1, V2 > Vth2 , V3 > Vth3 and V4 > Vth4 (all supplies over their corresponding thresholds)---> RSTB is de-asserted after reset timeout period (Trp).• MRIB goes to “LOW” to force “Reset” ----> RSTB is asserted immediately.• WDI does not make any transition during watchdog timeout period (Twd) ---->RSTB is asserted for a duration of reset timeout period (Trp).• One of the supplies drops below its corresponding threshold (in this case V3)---->RSTB is asserted immediately.V1V2V3V4MRIB WDIV1RSTBResetB Timeout DelayWatchdog Timeout Period10020030040050085 80 70 60 50 40 30 20 10 0 -10 -20 -30 -40D e g CRe s e t T i m e o u t ( m S e c )Reset Timeout vs. TemperatureResetTimeout Delay Vs.

General DescriptionThe MAX6332/MAX6333/MAX6334 microprocessor (µP)supervisory circuits monitor the power supplies in 1.8V to 3.3V µP and digital systems. They increase circuit reliability and reduce cost by eliminating external com-ponents and adjustments.These devices perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for a pre-set timeout period after V CC has risen above the reset threshold. The only difference among the three devices is their output. The MAX6333 (push/pull) and MAX6334(open-drain) have an active-low RESET output, while the MAX6332 (push/pull) has an active-high RESET out-put. The MAX6332/MAX6333 are guaranteed to be in the correct state for V CC down to 0.7V. The MAX6334 is guaranteed to be in the correct state for V CC down to 1.0V.The reset comparator in these ICs is designed to ignore fast transients on V CC . Reset thresholds are factory-trimmable between 1.6V and 2.5V, in approximately 100mV increments. There are 15 standard versions available (2,500 piece minimum-order quantity); con-tact the factory for availability of nonstandard versions (10,000 piece minimum-order quantity). For space-criti-cal applications, the MAX6332/MAX6333/MAX6334come packaged in a 3-pin SOT23.ApplicationsPentium II™ Computers Computers ControllersIntelligent InstrumentsCritical µP/µC Power Monitoring Portable/Battery-Powered Equipment AutomotiveFeatures♦Ultra-Low 0.7V Operating Supply Voltage♦Low 3.3µA Supply Current♦Precision Monitoring of 1.8V and 2.5V Power-Supply Voltages ♦Reset Thresholds Available from 1.6V to 2.5V,in Approximately 100mV Increments ♦Fully Specified over Temperature♦Three Power-On Reset Pulse Widths Available (1ms min, 20ms min, 100ms min)♦Low Cost♦Three Available Output Structures: Push/Pull RESET , Push/Pull RESET, Open-Drain RESET ♦Guaranteed RESET/RESET Valid to V CC = 0.7V (MAX6332/MAX6333)♦Power-Supply Transient Immunity ♦No External Components ♦3-Pin SOT23 Package♦Pin Compatible with MAX809/MAX810 and MAX6326/MAX6327/MAX6328MAX6332/MAX6333/MAX63343-Pin, Ultra-Low-Voltage, Low-PowerµP Reset Circuits________________________________________________________________Maxim Integrated Products119-1411; Rev 2; 12/05Ordering Information* These devices are available in factory-set V CC reset thresh-olds from 1.6V to 2.5V, in approximately 0.1V increments.Choose the desired reset threshold suffix from Table 1 and insert it in the blanks following “UR” in the part number.Factory-programmed reset timeout periods are also available.Insert the number corresponding to the desired nominal reset timeout period (1 = 1ms min, 2 = 20ms min, 3 = 100ms min) in the blank following “D” in the part number.

The Typical Operating Characteristics show the Maximum Transient Duration vs. Reset Comparator Overdrive graph. The graph shows the maxi-mum pulse width that a negative-going V CC transient may typically have without issuing a reset signal. As the ampli-tude of the transient increases, the maximum allowable pulse width decreases.Ensuring a Valid Reset OutputDown to V CC = 0When V CC falls below 1V and approaches the minimum operating voltage of 0.7V, push/pull-structured reset sinking (or sourcing) capabilities decrease drastically.High-impedance CMOS-logic inputs connected to the RESET pin can drift to indeterminate voltages. This does not present a problem in most cases, since most µPs and circuitry do not operate at V CC below 1V. For the MAX6333, where RESET must be valid down to 0,adding a pull-down resistor between RESET and GND removes stray leakage currents, holding RESET low (Figure 2a). The pull-down resistor value is not critical;100k Ωis large enough not to load RESET and small enough to pull it low. For the MAX6332, where RESET must be valid to V CC = 0, a 100k Ωpull-up resistor between RESET and V CC will hold RESET high when V CC falls below 0.7V (Figure 2b).Since the MAX6334 has an open-drain, active-low out-put, it typically uses a pull-up resistor. With this device,RESET will most likely not maintain an active condition,but will drift to a non-active level due to the pull-up resistor and the reduced sinking capability of the open-drain device. Therefore, this device is not recommend-ed for applications where the RESET pin is required to be valid down to V CC = 0.* Factory-trimmed reset thresholds are available in approximately 100mV increments, with a ±1.8% room-temperature variance.Table 1.
