Abstract:
A load drive control device includes a driver that drives a load which is operable by a DC drive and a pulse modulation drive, a protecting section that detects an electric current flowing in the driver, a temperature detecting section that detects a high temperature state of the driver, and a control section that determines whether the load is operated by the DC drive or the pulse modulation drive, based on outputs from the protecting section and the temperature detecting section. The control section switches the driver in the DC drive and measures the electric current flowing in the driver when a temperature equal to or higher than a predetermined temperature is detected during the pulse modulation drive.
