    Abstract: A method for selecting a power source for a load is provided. The method includes monitoring the primary power source, when the primary power source is providing power to the load, determining if a condition of the primary power source crosses a first threshold, when the condition crosses the first threshold, turning on a first power field effect transistor to couple a back-up power source to the load through a second power field effect transistor, when the primary power source is not providing power to the load, determining if a condition of the primary power source crosses a second threshold, and when the condition crosses the second threshold, switching off the first power field effect transistor to couple the primary power source to the load through a third power field effect transistor.

    Abstract: A method is provided. The method comprises determining configuration data; wherein the configuration data comprises a resistance of a bypass circuit coupled between a remote radio head and a power cable; using the configuration data, determining the resistance of the power cable coupling a programmable power supply to the remote radio head mounted on a mounting structure, comprising: entering a calibration mode; setting an output voltage of the programmable power supply; measuring an output current of the programmable power supply; storing the output current; and determining the cable resistance; and storing the resistance of the power cable.

    Abstract: A circuit for selecting between a primary power source and a back-up power source is provided in one embodiment. The circuit includes a first port configured to be coupled to a primary power source, a second port configured to be coupled to a back-up power source, a third port configured to be coupled to provide power to a load. The circuit also includes first and second power field effect transistors (FET) coupled between the second port and the third port, a third power FET coupled between the first port and the third port, and 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. The circuit further includes an opto-isolator coupled to a control input of the first power FET and a controller, coupled to the opto-isolator, that selectively turns on and off the opto-isolator.
