Abstract

A voltage detector to sense deviations of instantaneous value of a monitored voltage from a desired value is provided. The system includes a reference voltage source for providing a reference voltage. A divider responsive to the monitored voltage and the reference voltage divides the reference voltage by the monitored voltage. Thereafter a window comparator responsive to an output of the divider produces an indication when the output of the divider is either higher than some predetermined high value or lower than some predetermined low value.
