Abstract:
A driver and protection circuit for driving a power switch is disclosed. The driver and protection circuit includes a fault detection block configured to detect a discrepancy between a reference drive signal and a measured voltage at a gate of the power switch. The driver and protection circuit also includes a short circuit detection block configured to detect a gate-to-source short circuit or a gate-to-drain short circuit of the power switch. The driver and protection circuit further includes a latch coupled to the fault detection block and the short circuit detection block to selectively turn off an output driver coupled to the gate of the power switch when a fault or a short circuit is detected, and wherein the latch is configured to send a diagnostic signal when the fault or the short circuit is detected.

Claim (Index 23):
A method for driving a power switch, the method comprising:\n detecting a discrepancy between a reference drive signal and a measured voltage at a gate of the power switch, wherein detecting the discrepancy comprises comparing the measured voltage at the gate of the power switch with a gate monitoring low threshold voltage or a gate monitoring high threshold voltage; detecting a gate-to-source short circuit or a gate-to-drain short circuit of the power switch; and selectively turning off an output driver coupled to the gate of the power switch when a fault or a short circuit is detected, wherein selectively turning off the output driver comprises turning off the output driver if the measured voltage at the gate of the power switch is less than or equal to the gate monitoring low threshold voltage when the reference drive signal is a turn-on order.
