摘要

It is an object to suppress the influence of a noise pulse with a switching operation of a power switching element. A pulse generator (1) alternately outputs a pulse train having two pulses to outputs (A) and (B) synchronously with a signal input to a terminal (HIN). The pulse train is level shifted through switching elements (2) and (3) and resistive elements (8) and (9) which constitute a set of level shift circuits and is input to a flip-flop circuit (4). An output signal of the flip-flop circuit (4) is input to a control electrode of a power switching element (21) through a buffer circuit (35).
