Abstract (en)
[origin: WO9963423A1] The present invention relates to a power supply interface for coupling a first or a second power supply (14, 15) to a processing circuit of a computing device. The processing circuit, which is normally powered by the first supply, includes a processor (3) which generates a power supply control signal when power is to be supplied by the second supply (15). The power supply interface includes first and second power supply inputs (11, 12) which are connected to the main supply and backup supply respectively. A power supply output is coupled to the processing circuit and a detector is also provided for detecting the power supply control signal. A switching device (5) responds to the detector to selectively couple the second power supply input to the power supply output.
