Abstract
According to a drive control signal for controlling a semiconductor element to be turned on and off, a current output circuit supplies an output current for charging a gate when the semiconductor element is turned on. A Miller voltage detection circuit outputs a detection signal for a constant voltage period during which a temporal change rate of a gate voltage is lower than a threshold value. Based on a drive control signal and a detection signal, a signal generation circuit generates a capability change signal for controlling a current output capability of the current output circuit. The signal generation circuit generates the capability change signal such that the current output capability is increased upon detection of the constant voltage period by the Miller voltage detection circuit, after the semiconductor element is instructed to be turned on by a level change of the drive control signal.
