ABSTRACT:
A pulse generation part outputs a first ON pulse signal for turning a switching device on to a control part on based on the leading edge of a signal from the outside of a semiconductor device. The pulse generation part subsequently outputs a second ON pulse signal for turning the switching device on to the control part based on the same leading edge of the signal as the first ON pulse signal after a lapse of prescribed time after outputting the first ON pulse signal. Even if the control part cannot output an ON signal to the switching device based on the first ON pulse signal, the control part can output an ON signal based on the second ON pulse signal.
