Abstract
An electronic system is provided that includes a plurality of power consuming electronic circuits and a power management system that interfaces a power supply to the plurality of power consuming electronic circuits. The power management system includes a power level detect circuit that includes a voltage level detector circuit that receives an analog voltage level signal indicative of a level of voltage provided from the power supply. The power level detect circuitry also includes digital encoding circuitry that encodes the analog voltage level signal as a digital powered level signal also indicative of the level of the power supply voltage. Each of the power consuming electronic circuit includes configuration circuitry to receive the digital power level signal and to configure operation of that particular power consuming electronic circuit responsive to the digital power level signal.
