Abstract
An object is to provide a technique capable of mitigating the influence of external noise input to a semiconductor device. A semiconductor device includes semiconductor elements of multiple phases, control ICs of multiple phases that control driving of the semiconductor elements of multiple phases, respectively, and a plurality of control terminals provided for each phase and connected to the control ICs. In each phase, the plurality of control terminals includes input signal terminals, control power supply positive terminals connected to a positive side of control power supplies that supply power to the control ICs, and a plurality of control power supply GND terminals connected to reference potential of the control power supplies.
