記載の負荷駆動制御装置。[Claims for Utility Model Registration] (1) A DC power supply circuit that steps down and rectifies commercial AC, a power supply terminal into which DC from the DC power supply circuit is input, and an output that is output every time an external soft touch switch is turned on. A digital IC that has an output terminal whose voltage level is inverted between high and low levels, and a reset terminal that sets the output terminal to a low level when an external reset signal is input, and a digital IC that operates with a high level signal from the output terminal of the digital IC. a switching control circuit that drives the load with commercial alternating current; a current detection circuit that detects the current flowing through the load; and a current detection circuit that detects the current flowing through the load. A load drive control device comprising: a comparison circuit that outputs a reset signal to a reset terminal of a digital IC. (2) Claim 1 characterized in that the comparison circuit is provided with a time constant circuit of a resistor and a capacitor that stops outputting the reset signal for a short time when the load starts.
The load drive control device described.
