ABSTRACT:
A power consumption control device for detecting output of a pulse signal from an output terminal of an oscillator as an operation monitoring target and outputting a power consumption reduction signal when the pulse signal is not detected in a predetermined period of time, includes a p-type transistor and an n-type transistor which are connected in series and have a gate to which the output terminal is connected, and detecting means for detecting a through current flowing through the p-type transistor and n-type transistor, and outputs a power consumption reduction signal when the through current is not detected in a predetermined period of time.
