Abstract
The invention discloses a device for detecting load state of driving power supply, the present invention can detect the load state of the driving power supply by using the parasitic capacitance, the pull-down resistor module inside the main control unit and the level detecting module in the circuit, without adding peripheral circuit. In this way, the actual product volume of the present invention does not increase, nor does it need to increase the hardware cost.
