摘要： A power supply circuit comprising a charge pump circuit supplies a supply voltage to a gate driver. A timing controller supplies a predetermined timing signal to a NAND circuit, a shutdown terminal of the charge pump circuit, and a gate shading circuit including a capacitor, a resistor, a NOT circuit, and a transistor. When this timing signal is high, the charge pump circuit makes a normal operation and the gate shading circuit is deactivated. When this timing signal is low, the charge pump circuit stops operating and the gate shading circuit is activated to drain an electric charge from the output of the charge pump circuit.

In addition, the overheat protection circuit 1 has, as the filter means, a resistor R7 and a capacitor C1 that are respectively connected to the emitter and the collector of the transistor P1.
