ABSTRACT:
A voltage detector monitors a power voltage level to see whether or not the power voltage level exceeds a predetermined voltage level, and comprises a reference voltage producing circuit for producing a reference voltage level proportional to the predetermined voltage level, a monitored voltage producing circuit for producing a monitored voltage level proportional to the power voltage level, a voltage comparator operative to compare the monitored voltage level with the reference voltage level for producing an output signal indicative of status of the power voltage level, and a combination of a clamping resistor and a resistor provided in association with the voltage comparator for forcibly fixing the output signal to an inactive level until the power voltage level is sufficiently increased so that the voltage comparator never produces any error output signal.
