Semiconductor device with current sense element

Abstract

A semiconductor device, including a main switching element having a gate terminal and an emitter terminal, a sense switching element connected to the main switching element for detecting a current flowing through the main switching element, and a voltage division circuit connected between the gate terminal and the emitter terminal of the main switching element. The voltage division circuit includes a first resistor and a second resistor connected in series. A connection point of the first resistor and the second resistor is connected to the sense switching element, so that a voltage applied to the gate terminal of the main switching element is divided by the voltage division circuit, and a portion of the voltage is applied to the sense switching element.
