Abstract
A power switch control circuit is disclosed. A sensor circuit may determine a leakage current of a power switch coupled to a power supply signal and a power terminal of a circuit block. The power switch may be configured to selectively couple or decouple the circuit block from the power supply signal using a switch control signal. The switch control circuit may, in response to receiving a request to open the power switch, determine a target voltage level that is greater than a voltage level of the power supply signal for the switch control signal using the leakage current, and transition the switch control signal from an initial voltage to the target voltage level.
