Abstract
A driver circuit may be configured to control a power switch. The driver circuit may comprise an output pin configured to deliver signals to a gate of the power switch to control an ON/OFF state of the power switch, and a comparator configured to compare a gate-to-source voltage of the power switch to a first threshold when the power switch is ON and to compare the gate-to-source voltage of the power switch to a second threshold when the power switch is OFF.
