Abstract
Disclosed are a circuit and a method for controlling dynamic in-rush current in a power management circuit. The circuit includes a current limiting unit having a first quantity of sleep mode devices. A voltage drop minimization unit is coupled to the current limiting unit and has a second quantity of sleep mode devices. The second quantity of sleep mode devices is greater than the first quantity of sleep mode devices. A sequential enabling unit is coupled to both the current limiting unit and the voltage drop minimization unit. The sequential enabling unit is configured to turn on the voltage drop minimization unit after the current limiting unit in accordance with a predetermined delay.
