Abstract
A load switch circuit includes a power transistor. A first terminal is configured to receive a power supply voltage, and a second terminal is the output terminal of the load switch circuit and is coupled with an external inductive load. A clamping module includes at least a mutually coupled clamping unit and a driving unit. The clamping unit includes a voltage-current converter and a first resistor, the first resistor coupled between the output terminal of the voltage-current converter and the second terminal of the power transistor. The positive input terminal of the voltage-current converter receives the power supply voltage, and the negative input terminal is coupled to the second terminal of the power transistor.
