SEMICONDUCTOR DEVICE

摘要

The present invention is provided to easily manufacture an IPD as any of a high-side switch and a low-side switch. A level shifting circuit is coupled to an input terminal, a first terminal, and a grounding terminal. Drive power of the level shifting circuit is supplied from the first terminal. An output signal of the level shifting circuit is input to a driver circuit. The driver circuit is coupled to the first terminal and a second terminal. Drive power of the driver circuit is supplied from the first terminal. A transistor has a gate electrode coupled to the driver circuit, a source coupled to the second terminal, and a drain coupled to a third terminal.
