A user device is provided. The device includes a main power supply, and an auxiliary power supply. The main power supply provides a main power. The auxiliary power supply cuts off the main power according to a power level of the main power supply and provides an auxiliary power upon Sudden Power-Off (SPO).

Auxiliary power supply and user device including the same

A circuit can include a supercapacitor switch including first and second terminals, that is configured to electrically couple the terminals to one another in a closed position and to electrically de-couple the terminals from one another in an open position responsive to a supercapacitor switch control signal. A first supercapacitor has a first terminal that is electrically coupled to the first terminal of the supercapacitor switch and has a second terminal that is electrically coupled to a reference voltage. A second supercapacitor has a first terminal that is electrically coupled to the second terminal of the supercapacitor switch and has a second terminal that is electrically coupled to the reference voltage.
