Abstract
To realize a reduction in the number of parts in a system including a driver IC (semiconductor device). A high potential side power supply voltage is applied to a power supply application area. A high side area is formed with a circuit which includes a driver driving a high side transistor and is operated at a boot power supply voltage with a floating voltage as a reference. A low side area is formed with a circuit operated at a power supply voltage with a low potential side power supply voltage as a reference. A first termination area is disposed in a ring form so as to surround the power supply application area. A second termination area is disposed in a ring form so as to surround the high side area.
