Abstract
For sequencing of power rails, a plurality of switches, which operate independently of each other, are operable to control delivery of power from an input power rail to an output power rail. The delivery of the power is controlled by a control input. A time delay circuit is operable to delay the control input by a time period. An input discrete component, coupled in series with the delay circuit, is configurable to adjust the time period. A fast discharge circuit is enabled to override the time period on a trailing edge of the output power rail. A discharge circuit that is coupled to the output power rail includes an output discrete component, the component being selectable to control a decay rate of the output power rail.
