Summary:A circuit and method for digital controlling the slew rate of load voltage are provided. The circuit is comprised of a digital slew-rate control unit that utilizes a feedback signal to generate control signals where the feedback signal indicates the observed rate of voltage change on the load. The circuit is further comprised of a load driver circuit that is operated by the control signals and provides a slew-rate controlled output voltage used to operate a load switch, where the load switch provides power to the load. The circuit is configured to operate the load switch using a slew-rate controlling driver, depending on the state of the load switch transition, and a non-controlling driver.
