1. An electronic apparatus comprising:
a memory configured to store control information;
a housing including a surface configured to interface with a power transfer surface of a power feeding unit;
power receiving circuitry configured to receive power that is fed from the power feeding unit in a non-contact manner;
protection circuitry configured to vary a power receiving voltage of the power received by the power receiving circuitry; and
a controller configured to control operation of the protection circuitry to be put in a first state when the power receiving voltage exceeds a first threshold that is a predetermined protection setup voltage, and to switch operation of the protection circuitry to a second state when the power receiving voltage rises above a second threshold while the protection circuitry is operating in the first state.
