5V/3.3V or Adjustable, Low-Dropout, Low IQ, 200mA Linear Regulators
_______________General Description
The MAX882/MAX883/MAX884 linear regulators maximize battery life by combining ultra-low supply currents and low dropout voltages. They feature 200mA output current capability at up to +125°C junction temperature and come in a 1.5W SOIC package. The 1.5W package (compared to 0.47W for standard SOIC packages) allows a wider operating range for the input voltage and output current. The MAX882/MAX883/MAX884 use a Pchannel MOSFET pass transistor to maintain a low 11µA (15µA max) supply current from no-load to the full 200mA output. Unlike earlier bipolar regulators, there are no PNP base current losses that increase with output current. And, in dropout, the MOSFET does not suffer from excessive base currents that occur when PNP transistors go into saturation. Typical dropout voltages are 220mV at 5V and 200mA, or 320mV at 3.3V and 200mA. The MAX882 features a 7µA standby mode that disables the output but keeps the reference, low-battery comparator, and biasing circuitry alive. The MAX883/MAX884 feature a shutdown (OFF) mode that turns off all circuitry, reducing supply current to less than 1µA. All three devices include a low-battery-detection comparator, foldback current limiting, reverse-current protection, and thermal overload protection. The output is preset at 3.3V for the MAX882/MAX884 and 5V for the MAX883. In addition, all devices employ Dual Mode™ operation, allowing user-adjustable outputs from 1.25V to 11V using external resistors. The input voltage supply range is 2.7V to 11.5V. For low-dropout linear regulators with output currents up to 500mA, refer to the MAX603/MAX604 data sheet.

MAX706中文简介
功能监控器MAX705/706/813中文资料。
概述MAX705/706/813L是一组CMOS监控电路，能够监控电源电压、电池故障和微处理器(MPU或mP)或微控制器(MCU或mC)的工作状态。
将常用的多项功能集成到一片8脚封装的小芯片内，与采用分立元件或单一功能芯片组合的电路相比，大大减小了系统电路的复杂性和元器件的数量，显著提高了系统可靠性和精确度。
该系列产品采用3种不同的8脚封装形式：DIP、SO和mMAX。
主要应用于：微处理器和微控制器系统；嵌入式控制器系统；电池供电系统；智能仪器仪表；通信系统；寻呼机；蜂窝移动电话机；手持设备；个人数字助理(PDA)；电脑电话机和无绳电话机等等。
功能说明RESET/RESET操作复位信号用于启动或者重新启动MPU/MCU，令其进入或者返回到预知的循环程序并顺序执行。
一旦MPU/MCU处于未知状态，比如程序“跑飞”或进入死循环，就需要将系统复位。
对于MAX705和MAX706而言，在上电期间只要Vcc大于，就能保证输出电压不高于的低电平。
在Vcc上升期间RESET维持低电平直到电源电压升至复位门限或以上。
在超过此门限后，内部定时器大约再维持200ms后释放RESET，使其返回高电平。
无论何时只要电源电压降低到复位门限以下(即电源跌落)，RESET引脚就会变低。
如果在已经开始的复位脉冲期间出现电源跌落，复位脉冲至少再维持140ms。
在掉电期间，一旦电源电压Vcc降到复位门限以下，只要Vcc不比还低，就能使RESET维持电压不高于的低电平。
MAX705和MAX706提供的复位信号为低电平RESET，而MAX813L提供的复位信号为高电平RESET，三者其它功能完全相同。
有些单片机，如INTEL的80C51系列，需要高电平有效的复位信号。
看门狗定时器MAX705/706/813L片内看门狗定时器用于监控MPU/MCU的活动。
如果在内WDI端没有收到来自MPU/MCU 的触发信号，并且WDI处于非高阻态，则WDO输出变低。

MAX6822LUK-T中文资料
General DescriptionThe MAX6821–MAX6825 are low-voltage microprocessor (µP) supervisory circuits that combine voltage monitor-ing, watchdog timer, and manual reset input functions in a 5-pin SOT23 package. Microprocessor supervisory cir-cuits significantly improve system reliability and accura-cy compared to separate I Cs or discrete components.These devices assert a reset signal whenever the moni-tored voltage drops below its preset threshold, keeping it asserted for a minimum timeout period after V CC rises above the threshold. In addition, a watchdog timer moni-tors against code execution errors. A debounced manual reset is also available. The MAX6821–MAX6825 monitor voltages from +1.8V to +5.0V. These outputs are guaran-teed to be in the correct state for V CC down to +1.0V.Nine preprogrammed reset threshold voltages are available (see T hreshold Suffix Guide ). The MAX6821,MAX6822, and MAX6823 all have a manual reset input and a watchdog timer. The MAX6821 has push-pull RESET, the MAX6822 has open-drain RESET , and the MAX6823 has push-pull RESET . The MAX6824 has a watchdog timer and both push-pull RESET and push-pull RESET. The MAX6825 has a manual reset input and both push-pull RESET and push-pull RESET. The Selector Guide explains the functions offered in this series of parts.________________________ApplicationsFeatureso Monitors +1.8V, +2.5V, +3.0V, +3.3V, +5.0V Supplieso 140ms (min) Reset Timeout Delay o 1.6s Watchdog Timeout Period(MAX6821/MAX6822/MAX6823/MAX6824)o Manual Reset Input(MAX6821/MAX6822/MAX6823/MAX6825)o Three Reset Output OptionsPush-Pull RESET Push-Pull RESET Open-Drain RESETo Guaranteed Reset Valid to V CC = +1.0V o Immune to Short Negative V CC Transients o No External Components o Small 5-Pin SOT23 PackagesMAX6821–MAX6825Low-Voltage SOT23 µP Supervisors withManual Reset and Watchdog Timer________________________________________________________________Maxim Integrated Products1Pin Configurations19-1868; Rev 1; 1/01Ordering InformationThreshold Suffix Guideto complete the part number.minimum order increment.

TheMAX6821–MAX6825 µP supervisory circuits assert a reset to prevent code-execution errors during power-up, power-down, and brownout conditions. Whenever V CC falls below the reset threshold, the reset output asserts low for RESET and high for RESET. Once V CC exceeds the reset threshold, an internal timer keeps the reset output asserted for the specified reset timeout period (t RP ); after this interval, reset output returns to its original state (see Figure 2).Manual Reset InputMany µP-based products require manual reset capabil-ity, allowing the operator, a test technician, or external logic circuitry to initiate a reset. On the MAX6821/MAX6822/MAX6823/MAX6825, a logic low on MR asserts a reset. Reset remains asserted while MR is low, and for the timeout period (140ms min) after itven with CMOS logic levels or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual reset function;external debounce circuitry is not required. If MR is dri-ven from long cables or the device is used in a noisy environment, connect a 0.1µF capacitor from MR to GND to provide additional noise immunity.Watchdog InputIn the MAX6821–MAX6824, the watchdog circuit moni-tors the µP ’s activity. I f the µP does not toggle (low to high or high to low) the watchdog input (WDI) within the watchdog timeout period (1.6s nominal), reset asserts for the reset timoeout period. The internal 1.6s timer can be cleared by either a reset pulse or by toggling WDI. The WDI can detect pulses as short as 50ns.While reset is asserted, the timer remains cleared and does not count. As soon as reset is released, the timer starts counting (see Figure 3).Disable the watchdog function by leaving WDI uncon-nected or by three-stating the driver connected to WDI.The watchdog input is internally driven low during the first 7/8 of the watchdog timeout period and high for the last 1/8 of the watchdog timeout period. When WDI is left unconnected, this internal driver clears the 1.6s timer every 1.4s. When WDI is three-stated or unconnected,the maximum allowable leakage current is 10µA and the maximum allowable load capacitance is 200pF.Applications InformationWatchdog Input CurrentThe MAX6821/MAX6822/MAX6823/MAX6824 WDI inputs are internally driven through a buffer and series resistor from the watchdog timer (Figure 1). When WDI is left unconnected, the watchdog timer is serviced within the watchdog timeout period by a low-high-low pulse from the counter chain. For minimum watchdog input current (minimum overall power consumption), leave WDI low for the majority of the watchdog timeout period, pulsing it low-high-low once within the first 7/8 of the watchdog timeout period to reset the watchdog timer. I f WDI is externally driven high for the majority of the timeout peri-od, up to 160µA can flow into WDI.Interfacing to µPs with Bidirectional Reset PinsSince the RESET output on the MAX6822 is open drain,it interfaces easily with µPs that have bidirectional reset pins, such as the Motorola 68HC11. Connecting the µP supervisor ’s RESET output directly to the microcon-troller ’s RESET pin with a single pullup resistor allows either device to assert reset (see Figure 4).Negative-Going V CC TransientsThese supervisors are relatively immune to short-dura-tion, negative-going V CC transients (glitches), which usually do not require the entire system to shut down.M A X 6821–M A X 6825Low-Voltage SOT23 µP Supervisors with Manual Reset and Watchdog Timer 6_______________________________________________________________________________________Figure 1. Functional DiagramResets are issued to the µP during power-up, power-down, and brownout conditions. The Typical Operating Characteristics show a graph of the MAX6821–MAX6825’s Maximum V CC Transient Duration vs. Reset Threshold Overdrive, for which reset pulses are not generated. The graph was produced using negative-going V CC pulses, starting at the standard monitored voltage and ending below the reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse width that a negative-going V CC transient can typically have without trigger-ing a reset pulse. As the amplitude of the transient increases (i.e., goes farther below the reset threshold),the maximum allowable pulse width decreases.Typically, a V CC transient that goes 100mV below the reset threshold and lasts for 20µs or less will not trigger a reset pulse.Watchdog Software ConsiderationsOne way to help the watchdog timer monitor software execution more closely is to set and reset the watch-dog input at different points in the program, rather than pulsing the watchdog input high-low-high or low-high-low. This technique avoids a stuck loop, in which the watchdog timer would continue to be reset inside the loop, keeping the watchdog from timing out.Figure 5shows an example of a flow diagram where the I /O driving the watchdog input is set high at the beginning of the program, set low at the beginning of every subroutine or loop, then set high again when the program returns to the beginning. I f the program should hang in any subroutine, the problem would quickly be corrected, since the I /O is continually set low and the watchdog timer is allowed to time out,causing a reset or interrupt to be issued. As described in the Watchdog Input Current section, this scheme results in higher time average WDI input current than does leaving WDI low for the majority of the timeout period and periodically pulsing it low-high-low.MAX6821–MAX6825Low-Voltage SOT23 µP Supervisors withManual Reset and Watchdog Timer_______________________________________________________________________________________7Figure 4.

内置了两个独立的滤波模块，可以配置成低通，高通，带通，带阻，全通滤波器。
中心频率或者截止频率的控制需要外接电阻以及6 Pin-Strapped 的输入特性来编程实现，然而，Q值仅用电阻连接实现。
各种各样类型的滤波器都可以实现（巴特沃斯，切比雪夫，椭圆滤波器等等）。
内部集成了两个运算放大器。
MAX265可以将中心/截止频率可以最高调到40Khz，然而，MAX266，通过使用一个低范围的fclk/fo比例系数，可以将fos 调到140Khz。
4MHZ系统时钟，可以通过一个晶振或是额外的源获得。
滤波器的操作电压为从±2.37v到±6.3v或者+5V的单电源供电。

fclk/fo编程输入（F0-F5）被两个滤波模块共用,然而，每个部分的fo仍然受到各自外接电阻的独立调节。
各个模块的的Q值也是受到各自的外接电阻的独立调节的。
MAX266使用比MAX265更低范围的取样比率（fclk/fo），这样就可以产生更高的信号带宽以及fo的可编程范围。
降低fclk/fo产生的影响主要就是比MAX265的滤波器参数的连续性稍微差了一些，但是这些不同可以通过使用图23所示的图形或是美信得滤波器软件来补偿。
