摘要:
A first monitor circuit 50 and a second monitor circuit 60 each having an identical configuration are provided in a voltage monitor. A threshold switching section 41 switches a threshold of each of switching units 51 and 61 provided in the respective monitor circuits 50 and 60 to a same value. Each of comparators 53 and 63 compares the threshold with a reference voltage to output a result of the comparison. A fault detecting section 42 compares the respective outputs from the comparators 53 and 63 with each other to detect a characteristic shift of the threshold of each of the monitor circuits 50 and 60.
摘要(中):
在电压监视器中设置具有相同结构的第一监视电路50和第二监视电路60。 阈值切换部分41将设置在各个监视电路50和60中的每个开关单元51和61的阈值切换到相同的值。 比较器53和63中的每一个将阈值与参考电压进行比较,以输出比较结果。 故障检测部分42将比较器53和63的各个输出彼此进行比较,以检测每个监视器电路50和60的阈值的特性偏移。
