Abstract
The invention addresses providing a semiconductor device that enables to reduce noise simultaneous with switching. A driver IC which is a semiconductor device includes a drive circuit which drives a control terminal of a PMOS drive stage which is a switching element, a noise detection circuit which detects noise in an output signal when switching (turning) the PMOS drive stage on or off, and a control circuit which control driving by the drive circuit based on the detected noise.
