Abstract
The aim of the present invention is to provide a power supply control system which enables an improvement in the response speed of the voltage sensor section to be achieved at a low level of power consumption. The present invention comprises: a voltage booster circuit for boosting voltage; a voltage sensor section which operates on the basis of voltage output from the voltage booster circuit; and a threshold value altering circuit which lowers a threshold value of the voltage sensor section when the voltage booster circuit is operating, and raises a threshold value of the voltage sensor section when the operation of the voltage booster circuit is halted.
