A horizontal MOSFET is arranged in parallel to a horizontal MOSFET and a portion of a return current IL which flows to a linear solenoid flows as a current to the horizontal MOSFET. Therefore, a current which flows to a parasitic transistor is reduced and it is possible to suppress the current which flows to the parasitic transistor provided in the horizontal MOSFET. Since the current which flows to the parasitic transistor is reduced, it is possible to prevent the erroneous operation and breakdown of a semiconductor device forming a synchronous rectification circuit. |
