The BQ51003 is a Qi (WPC v1.1) compliant wireless receiver IC for wireless power transfer. It has been developed for 2.5 Watt applications. The device provides the AC-DC power conversion while integrating the digital control required to comply with the Qi v1.1 communication protocol. By using near-field inductive power transfer, the receiver coil embedded in the portable device receives the power transmitted by the transmitter coil through mutually coupled inductors. The AC signal from the receiver coil is then rectified and regulated to be used as a power supply for down-system electronics.
