Abstract

A switching device (20) is formed to generate a ramp voltage by using a capacitor (48) formed on the semiconductor die (90) with the switching device (20). The switching device (20) drives a high-power device to conduct load currents for a load. The ramp voltage is used to gradually increase the drive that is applied to the high-power device in order to gradually increase the current conducted by the high-power device.
