Abstract
Circuitry includes a pair of switches arranged in series, and a gate driver. The gate driver, responsive to a magnitude of current through one of the switches exceeding a threshold, discharges a gate of the one through a first resistor. The gate driver also, responsive to a voltage across a parasitic inductance of the switch becoming zero, discharges the gate through a second resistor but not the first resistor.
