A semiconductor device includes an H-Bridge driver. The H-Bridge driver includes a first island on which a first power transistor and a second power transistor are mounted; a second island on which a third power transistor and a fourth power transistor are mounted; a third island on which a control circuit and a protection power transistor are mounted, the control circuit being configured to control the first, second, third and fourth power transistors, wherein the third island is allocated between the first island and the second island.
