Abstract

A controller includes first and second half bridge sense circuits coupled to a half bridge node. The half bridge node is coupled between a high side switch and a low side switch coupled to an input. A rising slew detection circuit is coupled to the first half bridge sense circuit to output a first slew detection signal in response to a rising slew event at the half bridge node. A falling slew detection circuit is coupled to the second half bridge sense circuit to output a second slew detection signal in response to a falling slew event at the half bridge node. A control circuit coupled to output a high side drive signal to the high side switch and a low side drive signal to the low side switch in response to the first slew detection signal, the second slew detection signal, and a feedback signal.
