Claim Text:
1. A circuit, comprising: at least one Insulated-Gate Bipolar Transistor (IGBT) having a gate, collector, and emitter; a first driver for the at least one IGBT, the first driver configured to provide a driving current to the gate of the IGBT; a load connected to the emitter of the at least one IGBT; a short-circuit protection circuit connected across the gate and the emitter of the at least one IGBT, wherein the short-circuit protection circuit is further connected to the first driver, wherein the short-circuit protection circuit comprises a switch to provide a strong pull-down to the at least one IGBT in response to detection of a short-circuit event in the circuit, and wherein the short-circuit protection circuit further comprises a capacitor and resistor that control a turn-off current provided to the gate of the at least one IGBT; and a current buffer connected across the switch and the at least one IGBT.
