Zusammenfassung:	A semiconductor device includes an output circuit and a switching element. The output circuit includes a switching element, a sense switching element, and a shunt breaking circuit. When an upper arm side switching element changes from an on-state to an off-state, a regenerative current flows from a load because of the regenerative operation of the load. In the output circuit, the shunt breaking circuit is located on the low potential side of a sense MOSFET in the sense switching element. As a result, a shunt of the regenerative current, which is generated at the time of the regenerative operation of the load, to the sense switching element is cut off by the shunt breaking circuit.
