Claim Text:
1. An integrated circuit for driving a first load switch wherein the first load switch powers a current load, the integrated circuit comprising: a first digital slew-rate control unit for generating control signals, wherein the first digital slew-rate control unit receives a first input signal and generates first control signals based on the first input signal and a feedback signal that indicates the rate of voltage change on the load; and a first load driver circuit operated by the first control signals and the first input signal, wherein the first load driver circuit comprises a large low impedance driver receiving said first control signals and a small current limited driver receiving said first input signal, wherein an output of the large low impedance driver is coupled with the output of the small current limited driver to generate a slew-rate controlled first output voltage for operating the first load switch.
