Adjustment of drive control based on a detection voltage of a transformer requires a loop time, and therefore high-speed processing of the adjustment is difficult. A semiconductor integrated circuit device includes a driving circuit that drives a power semiconductor device and a driving capability control circuit that controls a driving capability of the driving circuit. The driving circuit stops driving of the power semiconductor device based on an abnormal current detected from a sense current of the power semiconductor device. The driving capability control circuit controls the driving capability of the driving circuit based on a normal current detected from the sense current of the power semiconductor device.
