4-Pin 關P Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay

General Description The MAX821/MAX822 microprocessor (µP) supervisory circuits monitor power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits. The MAX821/

4引脚、微处理器电压监测器，引脚可设置上电复位超时周期

MAX821/MAX822微处理器(µP)监控电路可监控µP和数字系统中的电源。当与5V供电或3V供电电路一起使用时，它们无需外部元件，也不用进行调整，可实现非常可靠的低成本电路。MAX821/MAX822还提供上电复位超时延迟，可通过引脚选择1ms（最大值）、20ms（最小值）或100ms（最小值）。\n\n 这些器件执行单一功能：每当VCC电源电压下降到预设阈值以下时，它们都会将复位信号置位，并在VCC上升到复位阈值以上后，在引脚选择的复位超时延迟内将复位保持置位。两款器件的区别只在于MAX821具有低电平有效RESET输出（VCC低至1V时能处于正确的状态），而MAX822具有 • 引脚可选的精密上电复位延迟：1ms（最大值）、20ms（最小值）或100ms（最小值）\n• 对+3V至+5V电源电压进行精密监控\n• 电源电流：2.5µA\n• 在整个温度范围内（-40°C至+125°C）提供保证\n• 低至VCC = 1V时确保低电平有效RESET有效(MAX821)\n• 电源瞬变抗扰度\n• 无需外部元件\n• SOT143封装;
