Patent ID: 6844614

Claim:
A semiconductor integrated circuit that is connected to an external load and a power supply, comprising: a lead frame; a first lead wire connected to a high electric potential side of the power supply; a second lead wire connected to a high electric potential side of the external load; a third lead wire connected to a low electric potential side of the external load; a transistor that is one of a P-channel type and a PNP type, the P-channel type having a source connected to the first lead wire and having a drain connected to the second lead wire, and the PNP type having an emitter connected to the first lead wire and having a collector connected to the second lead wire; and a diode for circulating an electrical current and having a cathode and an anode, the cathode being connected to the second lead wire, and the anode being connected to the third lead wire, wherein the transistor and the diode are mounted on a single island of the lead frame.
