    • In a power supply monitoring device, a power supply voltage monitoring portion always monitors a power supply voltage supplied to a monitored circuit and outputs a voltage reduction signal when detecting that the power supply voltage is reduced below a predetermined threshold (e.g. a second voltage higher than a voltage guaranteeing a normal operation of the monitored circuit and lower than a rated voltage). A monitoring controller having received the voltage reduction signal determines whether or not an operational malfunction has occurred in the monitored circuit by comparing operation data of the monitored circuit with reference data of the monitoring controller itself. Also, the monitoring controller executes recovery processing (reset processing or reference data overwrite processing) suitable for the monitored circuit referring to a prestored recovery processing type specific to the monitored circuit when detecting an operational malfunction of the monitored circuit.
    • 在电源监视装置中,当检测到电源电压降低到预定阈值以下时,电源电压监视部分总是监视提供给被监测电路的电源电压并输出电压降低信号(例如,高于 一个电压,保证被监测电路的正常运行并低于额定电压)。 已经接收到电压降低信号的监视控制器通过将监视电路的操作数据与监视控制器本身的参考数据进行比较来确定监视电路中是否发生了操作故障。 而且,当检测到所监视的电路的操作故障时,监视控制器参考专用于被监测电路的预先存储的恢复处理类型,执行适合被监视电路的恢复处理(复位处理或参考数据重写处理)。
