bq51013 Wireless Power Receiver

Texas Instruments' integrated wireless power supply receiver, Qi (WPC) compliant

bq51013 Wireless Power Receiver Texas Instruments' bq51013 is an advanced, integrated, receiver IC for wireless power transfer in portable applications. The device provides the AC/DC power conversion while integrating the digital control required to comply with the Qi v1.0 communication protocol. Together with the bq500110 transmitter controller, the bq51013 enables a complete contact-less power transfer system for a wireless power supply solution. By utilizing near-field inductive power transfer, the receiver coil embedded in the portable device receives the power transmitted by the transmitter coil via 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.

The bqTESLA150LP low power wireless power evaluation kit from Texas Instruments is a high performance, easy-to-use development kit for the design of wireless power solutions. Consisting of a single-channel transmitter featuring the bq500110 along with a 5 V power supply receiver featuring the bq51013, the kit enables designers to speed development of their end applications.
