Texas Instruments Debuts Wireless Power Receiver Chip

Texas Instruments (News - Alert), a semiconductor company has unveiled its next generation of wireless power technology, bq51013 receiver integrated circuit, which the company claims to be 80-percent smaller than its previous receiver chip.

This designer friendly device poses a very tiny shape, making it easier for designers to implement wireless charging in their existing and new designs for portable consumer devices, including smartphones, gaming systems, digital cameras, and medical and industrial equipment.

This highly integrated device consolidates all three functions of rectification, voltage conditioning and digital control on one small 1.9-mm x 3-mm WCSP package.

In addition, this IC device supports up to 5 W 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. It also includes full-bridge synchronous rectification, voltage conditioning and wireless power control in a single device with built-in protection against voltage, current and temperature fault conditions, assures safe and reliable system operation.

Also, its 93-percent peak efficiency reduces thermal rise inside the system while allowing charge rates comparable to an AC adapter with interoperability between various charging pads and portable devices.

Sami Kiriaki, senior vice president over TI's Power Management business, said, "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."

According to Kiriaki, the designers can use the bq51013 to quickly integrate wireless power into existing and new applications with minimal impact to overall solution size.

The company is currently offering this the bq51013 wireless power receiver in a 1.9-mm x 3-mm WCSP package, priced at $3.50 in quantities of 1,000.

Earlier this month, TMCnet reported that Texas Instruments is the first semiconductor company to license Ethernet for Control Automation Technology (EtherCAT) for its ARM (News - Alert) and DSP+ARM-based embedded processors.
