Abstract
A circuit for providing back-up power includes a switching circuit configured to be coupled to a first power source and a second power source. The circuit includes a domain voltage level monitor circuit coupled with the first power source and the second power source and with output of the switching circuit. The circuit includes a dynamic level shifter circuit coupled with the first power source and the second power source and an output of the domain voltage level monitor. The circuit includes a double controlled latch circuit coupled with the first power source and the second power source and an output of the dynamic level shifter circuit. The double controlled latch circuit is configured to provide control signals to the switching circuit.
