Abstract

An eletronic system includes a power supply providing an operating voltage, and a reset circuit. The reset circuit includes a voltage sensing circuit, coupled to the power supply, for generating a control signal when the operating voltage drops below a predetermined voltage. A control circuit generates a rest signal in response to the control signal. Further circuitry provides power to the control circuit, independently of the power supply, when the operating voltage drops below the predetermined voltage.
