微处理器监控电路

ADM698/ADM699监控电路针对微处理器系统提供电源监控和看门狗定时功能。\n\n ADM698监控5 V VCC 电源，并且在上电和关断期间，以及低压“掉电”情况下，产生一个RESET脉冲。即使VCC低至1 V，也能保证RESET输出有效（逻辑低电平）。\n\n ADM699具有一个与ADM698相同的监控电路，另外还有一路看门狗定时器输入，用来监控微处理器的活动。如果看门狗输入在1秒的看门狗超时周期内未触发，则会强制RESET输出变为低电平。\n\n 两款器件均提供8引脚塑料DIP和16引脚SOIC两种封装。16引脚SOIC含有附加输出RESET（无反相 • 出众的MAX698/MAX699升级产品\n\n• 保证RESET置位（VCC = 1 V）\n\n• 低电源电流：0.6 mA\n\n• 4.65 V精密电压监控器;
