内置窗口看门狗、手动复位功能和低电平有效开漏复位输出的监控电路

ADM8323/ADM8324 内置电源监控电路，可以监控微处理器系统的电源电压和代码执行完整性。片内看门狗定时器可检查预设超时窗口内的活动。复位信号也可以由手动复位输入引脚连接的外部按钮开关置位。RESET输出为推挽(ADM8323)或开漏(ADM8324)。 看门狗故障会导致RESET引脚输出低电平。故障可由快速看门狗错误（看门狗脉冲间隔太短）或慢速看门狗错误（超时周期内没有看门狗脉冲）触发。这样可以有效地提供观察看门狗脉冲的窗口。看门狗超时从上一个看门狗输入(WDI)的下降沿开始。共有8个不同的看门狗窗口可用，如表5所示。 \n\n 每款器件均提供26种复位阈值选项， • 窗口看门狗，8个超时选项 \n\n• 26个复位阈值选项\n2.5 V至5 V（以100 mV递增） \n\n• 4个复位超时选项\n1 ms、20 ms、140 ms和1120 ms（最小值） \n\n• 手动复位输入;
