ABSTRACT:
A substrate voltage detecting circuit includes a detection node, a transistor responsive to a detected substrate voltage for changing a comparison voltage, a differential amplifier for comparing the comparison voltage with a prescribed reference voltage and outputting an enable signal when the comparison voltage exceeds the reference voltage, and a transistor turned on in response to the enable signal for fixing the reference voltage at an L level. The internal voltage detecting circuit further includes transistors for reducing current consumption. Consequently, the responsibility thereof is improved even with small power consumption.
