And to add to what trobbins said, a higher current through the 220 ohm resistor, would just about guarantee the transistor in line with it was subjected to an overcurrent (and would probably be damaged).
I'd be looking at that transistor, as well as your gate driver.
I can't see the circuit, I'm just giving you the low-down on what I'd do, from what you've said so far. Trace the circuit, and look for anything that may have CAUSED your driver failure.
