微处理器监控电路

MAX696/MAX697监控电路减少了微处理器(µP)系统中的电源监控和电池控制功能所需的复杂性和元件数量。这些功能包括微处理器复位和备用电池切换、看门狗定时器、CMOS RAM写保护和电源故障警告。与使用单独的IC或分立元件获得的结果相比，MAX696/MAX697显著提高了系统的可靠性和准确性。\n\n MAX696和MAX697采用16引脚封装，并执行六个功能：\n\n 上电、关断和掉电情况下的复位输出。该“低电平”复位的阈值可通过外部分压器进行调节。 如果可选的看门狗定时器在指定时间内未切换，则提供复位脉冲。 为低电平和看门狗故障情况单独的 • 可调低电平监视器和关断复位\n\n• 电源正常/复位时间延迟\n\n• 看门狗定时器——100ms、1.6s或可调\n\n• 元件数量最少\n\n• 待机电流：1µA\n\n• 备用电池电源切换(MAX696)\n\n• 芯片使能信号板载选通(MAX697)\n\n• 单独的监控器，监控有无电源故障或低电池电量警告;
