CHARGE AND DISCHARGE CONTROL CIRCUIT AND BATTERY DEVICE

摘要

Provided is a charge and discharge control circuit and a battery device which ensure high safety, even when a charger is reversely connected. The charge and discharge control circuit includes a consumption current increase circuit for supplying a current from a power supply terminal to a ground terminal, the consumption current increase circuit including a switch circuit configured to be turned on in response to a detection signal from a charger reverse connection detection circuit, which indicates that a charger is reversely connected.
