Abstract
A driver circuit generates a drive signal having a first and second voltage state for controlling a power transistor switch coupled to a power supply node. A control circuit operates to sense a supply voltage at the power supply node and compare the sensed supply voltage to one or more voltage thresholds. In response to the comparison, the control circuit adjusts a switching slope of the drive signal from the first voltage state to the second voltage state.
