Abstract
Generally, this disclosure provides systems and methods for a power switching system with a switching control circuit powered by a supply voltage derived from an input control signal. The system may include a power switch configured to electrically couple a device between a battery voltage and a ground, the device to be powered by the battery when the power switch is closed; a control circuit coupled to a gate port of the power switch, the control circuit configured to open and close the power switch by adjusting a gate driving signal provided to the gate port in response to a switching control signal provided to the control circuit; and a voltage conditioning circuit configured to generate a supply voltage based on the switching control signal, such that the supply voltage powers the control circuit.
