Classification: CPC H | IPC H

Claim 17:
18. A method of controlling a power switch, the method comprising:
delivering drive signals from an output pin of a driver circuit to a gate of the power switch to control ON/OFF switching of the power switch;
receiving an indication from a voltage detection circuit of a value of voltage at the gate of the power switch;
determining whether a voltage overshoot is present based on the value of the voltage at the gate of the power switch;
determining whether the voltage overshoot satisfies a voltage threshold;
determining whether an overload condition is present based on the voltage overshoot satisfying a voltage threshold; and
in response to determining that the overload condition is present, adjusting the drive signal delivered via the output pin to adjust an operation of the power switch.
