Abstract
An automotive electrical system provides power from two DC sources each connected to a separate group of integrity-protected (ASIL) loads. A third group of non-ASIL loads are connected to both power sources through a controllable isolator with first and second transistor arrays. The connection through the isolator also connects each ASIL group to the other DC source. A control circuit includes a plurality of drivers for driving the first and second transistor arrays into conduction. The control circuit is configured to cease driving at least a respective one of the first and second transistor arrays when a fault condition is detected in which current flow in at least one of the transistor arrays exceeds a threshold.
