TI unveils ‘industry’s smallest’ power receiver chip

1 min read

Texas Instruments' next generation of wireless power technology is 80% smaller than its previous receiver chip and, according to the company, the industry's smallest.

The device has been designed to make it easy to implement wireless charging in existing and new designs for portable consumer devices, such as smart phones, gaming systems, digital cameras, and medical and industrial equipment. The bq51013 receiver integrated circuit combines voltage conditioning and full wireless power control in a 1.9 x 3mm WCSP package. The circuit supports up to 5W of output power and, says TI, provides up to 93% efficient ac/dc power conversion. It is the only IC required between the receiver coil and system. "Smartphone and consumer electronics manufacturers are demanding wireless power, and TI is well positioned to help our customers drive widespread adoption of this technology that makes life easier for people on the go to charge their devices," said Sami Kiriaki, senior vice president over TI's Power Management business. "Designers can use the bq51013 to quickly integrate wireless power into existing and new applications with minimal impact to overall solution size."
