Abstract
A device including: a transistor having a collector-emitter junction connected in series or parallel to a current detection resistance for detecting current that flows through a current sensing terminal of a switching element; and an overshoot processing circuit connected between the current sensing terminal and a base of the transistor, which reduces overshoot of sense current flowing through the current detection resistance, the overshoot is caused by switching operation of the switching element, by controlling the transistor depending on current input from the current sensing terminal, is provided.
