An integrated fault circuit includes a fault switch interposed between an input power source and an electronic subsystem power bus. A power converter is connected to the electronic subsystem power bus and converts power derived therefrom to at least one voltage output to supply power to an electronic subsystem and at least one fault protection output controlling the fault switch. A fault detection circuit is operatively connected to detect an out of range current on the electronic subsystem power bus and has at least one fault detection output connected to the power converter. When the out of range current is detected on the electronic subsystem bus, the fault detection circuit instructs the power converter, via the at least one fault detection output, to open the fault switch, thereby isolating the input power from the electronic subsystem bus.
