Abstract

A circuit includes a first feedforward path configured to determine a state of a first power switch using a first gate control voltage from a gate driver and a source voltage of the first power switch, and to apply a gate driving voltage to a gate of the first power switch based on the determined state of the first power switch; and a first feedback path configured to provide a scaled value of a drain voltage of the first power switch and a scaled value of the source voltage of the first power switch to the gate driver, where the first feedforward path and the first feedback path are configured to provide a bi-directional gate interface coupled between the gate driver and the first power switch.
