Classification: CPC G  H | IPC G  H

Claim 15:
16. A method, comprising:
operating a driver channel of an integrated circuit by driving a gate terminal of a power transistor of the driver channel;
detecting whether a high-side overcurrent condition is present at the driver channel based on an output of a first comparator of an on-state testing circuit in a high-side overcurrent testing mode of the on-state testing circuit; and
detecting whether a low-side overcurrent condition is present at the driver channel based on the output of the first comparator of the on-state testing circuit in a low-side overcurrent testing mode of the on-state testing circuit; and
wherein in a high-side driver mode, an external load is coupled between a source terminal of the power transistor and ground, and a drain terminal of the power transistor is coupled to an external high voltage source,
wherein in a low-side driver mode, the external load is coupled between the external high voltage source and the drain terminal of the power transistor, the source terminal of the power transistor is coupled to ground.
