Abstract
Power supply voltage monitoring circuit includes: input terminal; output terminal; ground terminal; voltage dividing circuit generating first and second divided voltages from power supply voltage applied to the input terminal; reference voltage source generating reference voltage using the power supply voltage; regulator voltage source generating regulator voltage higher than the reference voltage using the power supply voltage; comparator generating first binary output signal by comparing the reference voltage with the first divided voltage, using the regulator voltage as driving source; first switching part having main conductive path connected between the output terminal and the ground terminal and responsive to the first binary output signal; and second binary converting part generating second binary output signal in response to the second divided voltage, using the reference voltage as driving source, wherein binary power supply voltage monitoring output signal is generated according to logical operation of the first and second binary output signals.
