Analog Devices Inc. ADM8321监控电路
Analog Devices ADM8321监控电路监控微处理器系统的电源电压和代码执行完整性。片内看门狗定时器不仅能提供上电复位信号，若微处理器未能在预设超时周期内发出选通脉冲，还能复位微处理器。复位信号也可以由外部按钮开关通过手动复位输入引脚置位。它特有看门狗输入、输出级配置（开漏与推挽）。该器件具有3.0V的复位阈值、1ms的复位超时（最小值）和1.6s的超时（典型值）。它采用5引脚SOT-23封装，功耗典型值仅为10µA，使其成为低功耗、便携式应用的理想选择。
The ADI ADM8321 Supervisory Circuit features a watchdog input, output stage configuration (open-drain and push-pull). This device comes with a reset threshold of 3.0V, a reset timeout of 1ms (minimum) and a timeout of 1.6sec (typical). It comes in a 5-lead SOT-23 package and typically consumes only 10μA, making it suitable for use in low power, portable applications.
