Abstract
Disclosed is an inrush current control circuit for controlling current into a high-current circuit block. The inrush current control circuit comprises a number of distributed switches and a digital control circuit coupled to at least one of the distributed switches. The digital control circuit is configured to switch a first group of the distributed switches in response to an enable/disable signal. The digital control circuit is further configured to switch a second group of the distributed switches after a first programmable delay. According to one embodiment, a method comprises switching a first group of distributed switches by a digital control circuit of an inrush current control circuit in response to an enable/disable signal, and switching a second group of the distributed switches by the digital control circuit after a first programmable delay, thereby resulting in regulation of a flow of an inrush current.
