Abstract

A driver IC includes a ring-shaped termination area, and a first area and a second area that are respectively arranged outside and inside the termination area on a layout. A sense MOS that is arranged between floating terminal and a first sense node and is driven at a power supply voltage is formed in the termination area. A fault detection circuit that detects presence of a fault when a voltage of the first sense node is higher than a decision voltage that has been deteLutined in advance in a period of time that a low side driver is driving a low side transistor into an ON state is formed in the first area.
