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 (504, 510) that utilizes a feedback signal (508) to generate control signals (in 501 and 502) where the feedback signal indicates the observed rate of voltage change on the load (505). The circuit is further comprised of a load driver circuit (503, 509) that is operated by the control signals and provides a slew-rate controlled output voltage used to operate a load switch (506, 507), 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. |
