SELECTION METHOD OF NEAR-FIELD COMMUNICATION AND WIRELESS CHARGING SHARED SENSOR MODULE, AND SELECTION CIRCUIT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a selection method of near-field communication and wireless charging shared sensor module, and a selection circuit therefor.SOLUTION: A selection method of near-field communication and wireless charging shared sensor module includes the steps of: providing a sensor module provided with a first coil and a second coil for respectively receiving a first frequency signal or a second frequency signal in a sensing way; judging whether the signal received by the sensor module in a sensing way to be the first frequency signal or the second frequency signal; and controlling to turn on a first chip unit to be electrically connected with the first coil according to the first frequency signal, or controlling to turn on a second chip unit to be electrically connected with the second coil according to the second frequency signal. Therefore, the purpose of integration of two functions of near-field communication and wireless charging in one portable electronic device can be realized.
