Abstract
A method and apparatus for selectively charging a secondary voltage rail includes selectively and partially charging a secondary voltage rail using at least one soft start power gate switch and using an initial power control indicator. The partially charged secondary voltage rail is selectively charged, using at least one main power gate switch, based on the initial power control indicator and a detected voltage on the secondary voltage rail. When the initial power control indicator is in a state representative of an initial power up command and when the detected voltage is greater than or equal to a predetermined voltage level, at least one main power gate switch is closed thereby charging the secondary voltage rail.
