Abstract
There is provided a current detection circuit including: a current detection unit that detects a control current flowing between a control terminal of a semiconductor element of voltage-controlled type having a current detection terminal, and a drive circuit; an overcurrent detection unit that detects an overcurrent based on a result of comparing a sense voltage with a sense reference voltage, the sense voltage corresponding to a sense current flowing through the current detection terminal; and an adjustment unit that adjusts the sense reference voltage based on a detection result of the current detection unit.
