Abstract
A semiconductor device includes a main power semiconductor switching element, a current sense semiconductor switching element and a current sense semiconductor switching element protection circuit. The main power semiconductor switching element drives a load by switching. The current sense semiconductor switching element detects current flowing in the main power semiconductor switching element. The current sense semiconductor switching element protection circuit is provided between a gate of the main power semiconductor switching element and a gate of the current sense semiconductor switching element so as to protect the gate of the current sense semiconductor switching element at a reference potential different from that of the gate of the main power semiconductor switching element.
