Abstract

An example circuit includes a voltage regulator, a controller, and a chain of switches. The voltage regulator is configured to generate a supply voltage, the supply voltage connected to each switch in the chain of switches, and generate a supply voltage status signal, the supply voltage status signal indicating a status of the supply voltage. The chain of switches includes a first switch configured to switch the supply voltage to a first subcircuit of a plurality of sub circuits based on the supply voltage status signal and one or more second switches configured to switch the supply voltage to one or more respective subcircuits of the plurality of subcircuits.
