Abstract
A system includes: a first power supply; a second power supply; a headswitch disposed between the first power supply and logic circuitry; an enable driver coupling the second power supply to a control terminal of the headswitch; and a voltage generator operable to adjust a control voltage from the second power supply to the control terminal of the headswitch in response to a first voltage level of the first power supply exceeding a reference voltage level.
