Abstract

A semiconductor device including a semiconductor switch circuit and a drive circuit. The semiconductor switch circuit includes a semiconductor switch and a temperature sensor for detecting a temperature in a periphery of the semiconductor switch. The drive circuit includes an overheating protection unit configured to, upon determining that the detected temperature of the semiconductor switch reaches an overheating protection temperature, perform overheating protection of the semiconductor switch and issue an overheating protection alarm signal. The drive circuit also includes an advance warning control unit configured to set a threshold temperature that is lower than the overheating protection temperature, and upon determining that the detected temperature reaches the threshold temperature, to output an advance warning signal before the overheating protection becomes operational. The overheating protection alarm signal and the advance warning signal are outputted from a same terminal of the drive circuit and are of different signal levels.
