TI Introduces Smallest Wireless Power Receiver Solution

Texas Instruments Inc. (TI) introduced its next generation of wireless power technology, the bq51013 wireless power receiver IC for portable consumer devices such as smart phones, gaming systems, digital cameras, along with medical and industrial equipment. The new receiver, which supports up to 5W of power, provides efficient ac to dc power conversion while integrating voltage conditioning and full wireless power control on a small 1.9 x 3mm WCSP package; thus reducing the PCB area by 80-percent from its first generation solution. With its small size, peak efficiency of 93-percent, and the only IC required between the receive coil and the system, the bq51013 allows designers to quickly integrate wireless power technology into their existing and new applications with minimal impact to solution size.

"Manufacturers need quick and efficient means of implementing wireless power into their solutions, as the adoption and demand of wireless power is quickly growing. TI is positioned to meet those needs and help OEMs bring the convenience of wireless charging to their consumers," said Masoud Beheshti, Worldwide Strategic Marketing Director of TI’s Power Management business. "Our solution is extremely small and offers 94-percent peak efficiency, which means it can be easily placed anywhere in the system. It opens up new possibilities for creating form factors and solutions which were not possible before."

The receiver and its associated transmitter solution, the bq5001100 are Wireless Power Consortium (WPC) Qi-compliant. This compliance assures interoperability between various charging pads and portable devices.

The bq51013 wireless power receiver is available now in a 1.8 x 3mm WCSP package, priced at $3.50 in quantities of 1,000.
