摘要： An electronic circuit includes a gate driver circuit. The gate driver circuit receives an input signal and a signal corresponding to a current through a switch, and produces, using the input signal, an output signal for controlling the switch. In response to the input signal being de-asserted, the gate driver circuit may turn the switch off at a normal turn-off rate when the current through the switch is less than an overcurrent (OC) threshold, and at an OC turn-off rate that is slower than the normal turn-off rate when the current through the switch is greater than the OC threshold.
