A circuit that automatically, seamlessly connects the higher (or the lower) of two power supplies to an output is described. The circuit does not incur a one diode drop when the two power supplies are at about the same voltage levels, and the unused power supply draws no stand-by current. Cross coupled transistor and cross coupled inverters are employed.
