Abstract:
A charging and discharging control circuit includes a switching circuit that controls the gate of a bidirectional conduction type field effect transistor; a first transistor of which the drain is connected to the drain of the bidirectional conduction type field effect transistor, the gate is connected to the source of the bidirectional conduction type field effect transistor, and the source and the back gate are connected to a first terminal of the switching circuit; and a second transistor of which the drain is connected to the source of the bidirectional conduction type field effect transistor, the gate is connected to the drain of the bidirectional conduction type field effect transistor, and the source and the back gate are connected to the first terminal of the switching circuit. The back gate of the bidirectional conduction type field effect transistor is connected to the first terminal of the switching circuit.
