Abstract
A power switch device includes a switch which is configured to switch a load signal between an on state and an off state. A first terminal and a second terminal of the power switch device are configured to provide a supply voltage to the power switch device. The second terminal is further configured to provide a control signal to the power switch device. The control signal is generated by disconnecting the second terminal from an external voltage source. A storage circuit of the power switch device is configured to capacitively store a status of the supply voltage. A control circuit of the power switch device is configured to control operation of the power switch device depending on the stored status of the supply voltage.
