ABSTRACT:
An over-charge protection FET and an over-discharge protection FET are connected in series with the rechargeable battery and turned ON or OFF by a control circuit. An ON-OFF switching device is connected between G and S of the over-charge protection FET and controlled by an output signal from the control circuit. An over-charge protection FET drain voltage input circuit is connected to the input side of the ON-OFF switching device. When the drain voltage of the over-charge protection FET is high, the input circuit sets the ON-OFF switching device to the ON state to forcibly set the over-charge protection FET to the OFF state.
