ABSTRACT:
Gate leakage in the DMOS transistor of a low-side driver device is detected and reported by utilizing a sense circuit to sense the voltage on the gate of the DMOS transistor, and by determining whether the voltage on the gate of the DMOS transistor has exceeded a predetermined value within a predefined period of time when the device is turned on.
