ABSTRACT:
A voltage monitor and method enables the monitoring of a DC input voltage. The input voltage is continuously scanned and compared to a predetermined threshold. The result of the comparison is periodically stored in a shift register along with previous scan results. When a predetermined number of stored scan results indicate an out of range input voltage, a digital output changes state to provide indication of the abnormal condition.
