Abstract
A circuit that allows selection of a power source among a plurality of power sources is disclosed. In an embodiment, either one or both voltage sources Vaux and Vapp may be available in a system. If both sources are available, then the circuit enables the system to use source Vaux. However, if only one of the two sources is available, then the circuit enables the system to use that available source.
