Abstract

A brown-out detection circuit having a time sequence control function comprises: a voltage divider (), a reference voltage source (), a comparator () and a time sequence control module (); wherein one terminal of the voltage divider () is connected to an external power supply, the other terminal of the voltage divider () is connected to a positive input of the comparator (), the reference voltage source () is connected to an inverted input of the comparator (), the time sequence control module () is connected to an output of the comparator (), an output of the time sequence control module () serves as an output of the brown-out detection circuit; when a duration of a power supply voltage lower than a reference voltage is not shorter than a preset time, the time sequence control module () controls the output of the brown-out detection circuit to be inverted from a high level to a low level.
