Abstract
A comparator circuit includes a comparator, which detects an abnormal voltage of a secondary battery, and uses PMOS transistors or NMOS transistors used as a differential pair. The comparator circuit includes a control circuit that is configured to control voltages of two input terminals of the comparator are to be equal to each other in a standby state in which an operation of the comparator circuit is in a stop state.
Claims5
