Abstract:
A method for driving an electronic device stably is provided. The electronic device includes a power supply circuit to which power is fed by power sequentially supplied from a contactless power feeding device, and a plurality of loads to which power is sequentially supplied from the power supply circuit. Further, a method for driving an electronic device stably is provided. The electronic device includes a power supply circuit to which power is fed by power supplied from a contactless power feeding device, and one or more loads to which the power supply circuit repeatedly supplies power. The power supply potential Vdd is restored to more than or equal to 90% of the initial potential Vdd0 within an interval in which the power supply circuit is not connected to a load; then, the next load may be connected to the power supply circuit, and may be driven.
