Claim 9:
10. A method for selecting a power source for a load, the method comprising:
monitoring a first power source;
when the first power source is providing power to the load, determining if a condition of the first power source indicates a fault condition;
when the fault condition is detected,
turning on a first power field effect transistor,
under control of a dual ideal diode-OR controller, coupling a second power source to the load through a second power field effect transistor and decoupling the first power source through a third power field effect transistor;

when the first power source is not providing power to the load, determining if the fault condition has been removed;
when the fault condition has been removed, switching off the first power field effect transistor such that the dual ideal diode-OR controller couples the first power source to the load through the third power field effect transistor.
