ABSTRACT:
A power-off controlling circuit and a power-off controlling method that control power-off of an integrated circuit based on the size of leakage currents. The power-off controlling circuit includes a model circuit section that includes a model circuit made by modeling a basic circuit of an integrated circuit, a voltage comparing circuit section that compares an output voltage charged by a leakage current occurred at the model circuit and a preset reference voltage, a decision circuit section that measures an arrival time until the output voltage reaches the reference voltage from the compared result and decides a size of the leakage current from the measured result, and a power-off controlling circuit section that controls power-off of the integrated circuit on the basis of the decided size of the leakage current.
