POWER-RECEIVING DEVICE, ELECTRONIC APPARATUS, AND CONTACTLESS POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow a power receiving device to directly involve in charge control of a battery, in a contactless power transmission system.

SOLUTION: A power-reception control device (50), provided in a power receiving device (40), includes a power reception side control circuit (52) that controls the operation of the power-receiving device (40), and a power supply control signal output terminal (TB1) for supplying a power supply control signal (ICUTX) that controls the power supply to a battery (94) to a charge control device (92). The power-reception side control circuit (52) controls the timing at which the power supply control signal (ICUTX) is output from the power supply control signal output terminal (TB1). Operation of the charge control device (92) is forcedly controlled by the power supply control signal (ICUTX).
