DRIVE DEVICE AND METHOD FOR CONTROLLING DRIVE DEVICE

WIPO Patent Application WO/2019/146149

A1

This drive device is provided with: a first gate driver circuit, which outputs, to a control terminal of a first transistor, a first control signal generated on the basis of a first positive power supply voltage of first positive power supply wiring, and a first negative power supply voltage of first negative power supply wiring, and which controls operations of the first transistor; a second gate driver circuit, which outputs, to a control terminal of a second transistor, a second control signal generated on the basis of a second positive power supply voltage of second positive power supply wiring, and a second negative power supply voltage of second negative power supply wiring, and which controls operations of the second transistor so that the first transistor and the second transistor complementarily turn on/off; and a first charge pump circuit, which generates, on the basis of the first control signal, the first negative power supply voltage having a polarity opposite to that of the first positive power supply voltage by having the potential of the output terminal as reference, and which applies the first negative power supply voltage to the first negative power supply wiring.
