TI Intros Smallest Wireless Power Receiver Chip

Texas Instruments Inc. (TI) has launched its next generation of wireless power receiver chip, which is 80 percent smaller than its predecessor. The tiny, highly integrated device makes it easy for designers to implement wireless charging in their existing and new designs for portable consumer devices, such as smart phones, gaming systems, digital cameras, and medical and industrial equipment.

The bq51013 receiver IC combines voltage conditioning and full wireless power control in a small 1.9x3mm WCSP package. The new circuit supports up to 5W of output power, provides up to 93 percent efficient AC/DC power conversion and 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 of 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."

The highly integrated and efficient wireless power receiver IC includes full-bridge synchronous rectification, voltage conditioning and wireless power control in a single device. Being Wireless Power Consortium (WPC) Qi-compliant, the receiver and its associated bq500110 transmitter IC are interoperable between various charging pads and portable devices.
