PROBLEM TO BE SOLVED: To provide systems, circuits and methods for protecting an insulated-gate bipolar transistor from short-circuit events.SOLUTION: A short-circuit protection circuit 804 including a switch, a resistor, a capacitor, and an optional current buffer provides a strong pull-down to an insulated-gate bipolar transistor Q1 in response to detecting a short-circuit event and then controls a rate at which turn-off current is decreased, thereby minimizing a peak voltage for the insulated-gate bipolar transistor Q1.SELECTED DRAWING: Figure 8 |
