具有看门狗和手动复位功能的监控电路，采用5引脚SC70和SOT-23封装

ADM823/ADM824/ADM825均为监控电路 ， 用来监控微处理器系统中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 。 复位信号也可以由一个外部按钮 ， 通过手动复位输入置位 。 三款器件具有不同的看门狗输入、手动复位输入和输出级配置组合，如表1所示。\n\n 这些器件提供7种复位阈值选项，可在2.19 V至4.63 V范围内选择。复位和看门狗超时周期分别固定为140 ms（最小值）和1.6秒（典型值）。\n\n ADM823/ADM824/ADM825提供5引脚SC7 • 2.5 V至5 V精密电源监控器\n\n• 7种复位阈值选项：2.19 V至4.63 V\n\n• 复位超时：140 ms（最小值）\n\n• 手动复位输入（ADM823、ADM825）;
