Abstract:
A short protection circuit for protecting a power switch. The short protection circuit has a transistor and compares a differential voltage between a first end of the power switch and a second end of the power switch to a threshold voltage of the transistor only when the power switch is in an ON state; and wherein when the differential voltage is higher than the threshold voltage, the short protection circuit turns off the power switch.
