Abstract
A power control device includes a first switch and a second switch. A first terminal of the first switch is configured to receive a first voltage signal in a first voltage domain, and a first terminal of the second switch is configured to receive a second voltage signal in a second voltage domain different from the a first voltage domain. A second terminal of the second switch is coupled to a second terminal of the first switch, and a control circuit is coupled to control terminals of the first switch and the second switch. The control circuit is configured to turn on the first switch in response to a decrease of a voltage level of the first voltage signal.
