Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

Well, it seems like lets be about to work out wireless charging spread to more places than ever before — Texas Instruments just unveiled its next-generation, Qi -compliant wireless power receiver chip today, that’s an entire eighty percent smaller than its previous chip. That promises to make it much more easier for manufacturers to implement in everything from cellphones to game consoles to digital cameras, and that small size apparently comes with none compromises, with it providing 5W of output power and a 93-percent peak efficiency that’s reminiscent of an AC adapter. Unfortunately, there’s no indication as to after we might see any actual devices that use the chip, but those must be coming before too long — the entire bq51013 wireless power package is now already available for for just $3.50 in quantities of one,000. Full press release is after the break.

Texas Instruments introduces industry’s smallest wireless power receiver chip

Easily integrates wireless charging technology into new and existing portable electronics

DALLAS, April, 18, 2011 /PRNewswire/ — Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced its next generation of wireless power technology, that is 80-percent smaller than TI’s previous receiver chip. The tiny, highly integrated device makes it easy for designers to implement wireless charging of their existing and new designs for portable consumer devices, equivalent to smart phones, gaming systems, digital cameras, and medical and industrial equipment.

The bq51013 receiver integrated circuit (IC) combines voltage conditioning and entire wireless power control in a small 1.9-mm x 3-mm WCSP package. The hot circuit supports as much as 5 W of output power, provides as much as 93-percent efficient AC/DC power conversion and is the sole IC required between the receiver coil and system. For additional information or to reserve samples of the bq51013, visit: www.ti.com/bq51013-pr.

“Smartphone and consumer electronics manufacturers are demanding wireless power, and TI is easily positioned to assist our customers drive widespread adoption of this technology that makes life easier for folk at the visit charge their devices,” said Sami Kiriaki, senior vp over TI’s Power Management business. “Designers can use the bq51013 to quickly integrate wireless power into existing and new applications with reduced impact to overall solution size.”

Key features and benefits

* Highly integrated and efficient wireless power receiver IC includes full-bridge synchronous rectification, voltage conditioning and wireless power control in one device.
* 1.9-mm x 3-mm WCSP package allows easy integration with minimal size impact. Device area is 80 percent not up to TI’s first-generation receiver.
* The receiver and its associated bq500110 transmitter IC are Wireless Power Consortium (WPC) Qi-compliant. This compliance ensures interoperability between various charging pads and conveyable devices.
* Built-in protection against voltage, current and temperature fault conditions, assures safe and reliable system operation.
* 93-percent peak efficiency reduces thermal rise contained in the system while allowing charge rates similar to an AC adapter.

Tools and support

TI offers a whole lot of tools and support to hurry the implementation of wireless power:

* bqTESLA150LP Wireless Power Evaluation Kit, which incorporates the bq51013 receiver and bq500110 transmitter: www.ti.com/bqTESLA150LP-pr
* bqTESLA150LP User Guide: www.ti.com/bqTESLA150LP-pr

Availability and pricing

The bq51013 wireless power receiver is accessible now in a 1.9-mm x 3-mm WCSP package, priced at $3.50 in quantities of one,000.
