This invention relates to a drive control circuit, its control method, medium, and switching circuit. The control method includes: controlling a power switch to start in an adaptive starting current identification mode; monitoring the starting current of the power switch; determining whether the starting current is within a preset range; and if not, adjusting the resistance of a digital potentiometer to bring the starting current within the preset range. This invention enables the automatic adjustment of the conduction speed of the power devices in the switching circuit based on the state of the downstream power circuit, thereby controlling the circuit's starting current and ensuring safe circuit startup.
