負荷駆動装置。 A drive control circuit 1 that is supplied with a measurement pulse signal and creates a control signal based on this measurement pulse signal.
0, 11, a load 5 having a time delay element, and a detection section 12 that detects the current supplied to this load from the drive control circuit, and determines an output abnormality based on a detection signal from this detection section. In the load driving device, the drive control circuits 10 and 11 calculate the magnitude of the current to be supplied to the load based on the supplied measurement pulse signal, and combine the current calculated current with the previously calculated current value. A load driving device that outputs an abnormality detection signal when the difference exceeds a predetermined value after the load delay time has elapsed.
