Abstract
The integrated circuit device includes a drive circuit and a regulator. The drive circuit outputs a drive signal to a switching element. A source power supply voltage the same in potential as a source voltage of a transistor as the switching element is input to the regulator, and the regulator generates a gate power supply voltage based on the source power supply voltage. The drive circuit has a level shifter for level-shifting a PWM signal based on the gate power supply voltage and the source power supply voltage. The drive circuit outputs the drive signal based on an output signal of the level shifter to the gate of the transistor.
