摘　　要：本文设计了一个低压系统下的过压欠压保护电路,该电路在运行的过程中,可以利用带隙基准的电路结构,全面提升输出电压的阈值精度,也相应控制了二极管在运行阶段中的低压条件.在电路的欠压保护机制下,设计出了一定的迟滞量,避免在系统运行环境下,预制附件出现反复关断的问题.This paper designs an overvoltage and undervoltage protection circuit in a low-voltage system,which can use the circuit structure of the bandgap reference to comprehensively improve the threshold accuracy of the output voltage during operation,and also control the low-voltage conditions of the diode in the operation stage.Under the undervoltage protection mechanism of the circuit,a certain amount of hysteresis is designed to avoid the problem of repeated shutdown of prefabricated accessories in the system operating environment.
