Patent ID: 11885845
Assignee: STMICROELECTRONICS S.R.L.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. An integrated circuit, comprising:
a driver channel configured to be selectively operated in a high-side driver mode or a low-side driver mode, the driver channel including:
a power transistor;
a drain output terminal coupled to a drain of the power transistor; and
a source output terminal coupled to a source of the power transistor;

wherein in the high-side driver mode, an external load is coupled between the source and ground, and the drain is coupled to an external high voltage source;
wherein in the low-side driver mode, the external load is coupled between the external high voltage source and the drain, the source is coupled to ground; and
an on-state test circuit coupled to the driver channel and including a first comparator and configured to be selectively operated in a high-side overcurrent testing mode and a low-side overcurrent testing mode, wherein the on-state test circuit is configured to detect a high-side overcurrent condition of the driver channel based on the first comparator in the high-side overcurrent testing mode and to detect a low-side overcurrent condition of the driver channel based on the first comparator in the low-side overcurrent testing mode.
