摘要:
Systems and methods for switching to a back-up power supply are provided. One such system includes a threshold detector circuit (102); a first switching circuit (108-2) for enabling access to a first power source, the first switching circuit comprising at least a first transistor; and a second switching circuit (108-1) for enabling access to a second power source, the second switching circuit comprising at least a second transistor; wherein the threshold detector is configured to cause the second switching circuit to enable access to the second power supply responsive to a voltage provided by the first power supply dropping below a predetermined threshold.
