Classification: CPC H  G | IPC G  H

Claim 12:
13. A circuit for switching between a first power source and a second power source, the circuit comprising:
a first port configured to be coupled to the first power source configured to operate at a first voltage level;
a second port configured to be coupled to the second power source configured to operate at a second voltage level;
a third port configured to be coupled to provide power to a load;
first and second power field effect transistors (FET) coupled between the first port and the third port;
a third power FET coupled between the second port and the third port;
a dual ideal diode-OR controller coupled between the second and third power FETs to selectively turn on and off the second and third power FETs;
a switch coupled to a control input of the first power FET;
a controller, coupled to the switch, that selectively turns on and off the switch;
wherein the controller monitors a condition of the circuit and, selectively changes the state of the switch based on the condition, and wherein the dual ideal diode-OR controller disables the second power FET and enables the third power FET so that power is provided to the third port from the second port via the third power FET when the condition indicates the circuit is in a first state.
