INTEGRATED CIRCUIT FOR WIRELESS POWER CHARGING AND METHOD FOR OPERATING THE INTEGRATED CIRCUIT

摘要

An integrated circuit for wireless charge according to an embodiment of the present invention includes a first wireless communication unit which supports a first wireless communication method; a second wireless communication unit which supports a second wireless communication method; a first path selection unit which selects one of first power input according to wired charge and second power input according to the wireless charge to receive power; a second path selection unit which selects one of third power input of a battery and fourth power input according to the wireless charge to receive the power; a power control unit which receives the power from one of the first path selection unit and the second path selection unit; and a control unit which controls the operation of the first path selection unit and the second path selection unit. Therefore, the present invention is provided to enable an existing WIFI/BT 4.0 combo IC to perform signaling in the wireless charge, thereby wirelessly charging the terminal in a dead battery situation.
