ABSTRACT:
A voltage potential monitoring circuit is operative to set a voltage potential threshold substantially independent of ambient temperature variation. The monitoring circuit includes a first circuit for generating a first current proportional to the voltage potential being monitored, and a second circuit responsive to the first circuit for generating a second current. The voltage potential threshold is set substantially as a function of the first and second currents. The monitoring circuit further includes a circuit responsive to the first and second currents for generating an undervoltage signal when the monitored voltage potential falls below the set voltage potential threshold. The voltage potential monitoring circuit has application in an electronic device which is operational over an ambient temperature range and includes a source of power for generating a voltage potential suitable for energizing the electronic device.
