ABSTRACT:
A supply-voltage detector having a low minimum operational voltage while having a large variation is combined with a supply-voltage detector having a high detection precision while having a high minimum operational voltage, so that the supply voltage is detected at a high accuracy without malfunctioning even on a low voltage. A system, such as a microcomputer, could then be reset when the detected supply voltage falls below a certain value. This combined circuit will improve the accuracy of detecting this supply voltage.
