Abstract
The present application relates to a gate driver including a zero-crossing detection circuit and a control signal generation circuit. The zero-crossing detection circuit receives a load current signal indicative of a load current of a power switch, detects a zero crossing of the load current, and generates a zero-crossing detection signal based on the detected zero-crossing. The control signal generation circuit receives an input control signal indicative of one of a turn-on and a turn-off of the power switch. If the input control signal is indicative of the turn-off of the power switch, the control signal generation circuit generates a turn-off signal based on the zero-crossing detection signal, determines if a time-out interval subsequent to the indication of the turn-off has expired, generates the turn-off signal regardless of the zero-crossing detection signal if the turn-off time interval has expired, and provides the turn-off signal to the power switch.
