Industry's first 10-W wireless power solution allows consumers to charge faster and cooler without plugging in

DALLAS, Nov. 19, 2014 /PRNewswire/ -- Designers of industrial, medical and personal electronics want devices to charge faster and more efficiently, while getting rid of all connectors. Today Texas Instruments (TI) (NASDAQ: TXN) provides a more efficient solution with the industry's first fully integrated 10-Watt wireless charging receiver and corresponding transmitter. The bq51025 and bq500215, both shipping in volume production, enable waterproof and dustproof portable designs and provide a faster, cooler charge to one- and two-cell (1S and 2S) Li-Ion batteries. The charging solution is also compatible with any 5-W Qi-compliant product in the market – allowing consumers the flexibility to charge in more places than ever before.

TI will demonstrate the new 10-W wireless charging solution at the Wireless Power Summit in Berkeley, Calif., Nov. 19-20.

Efficient wireless charging at 10-W
The bq51025 receiver supports a programmable output voltage of 4.5 V to 10 V and achieves up to 84 percent charging efficiency at 10-W when paired with TI's bq500215 wireless power transmitter, significantly improving thermal performance. The fully contained wireless power receiver solution measures only 3.60-mm by 2.89-mm, and can be designed into many portable industrial designs, ranging from point-of-sale (POS) scanners to handheld medical diagnostic equipment, and personal electronics, such as tablets and ultra-books.

The new bq500215 is a dedicated, fixed-frequency 10-W wireless power digital controller transmitter compatible with 5-W Qi receivers. The transmitter features an enhanced foreign object detection (FOD) method that detects objects before any power is transferred, and actively reduces power if excessive loss is detected.

Key features and benefits of bq51025/bq500215:

• Fast-charging receiver achieves up to 84 percent system efficiency at 10-W when combined with TI's bq500215 controller – enabling a fast charging experience for one- and two-cell battery powered electronics.
• Qi-compliant communications and control ensures compatibility with any Wireless Power Consortium Qi-certified transmitter or receiver up to 5W. The wireless charging solution's I2C communications interface allows better alignment of the receiver on the transmitter surface, as well as ability to send proprietary packets of data between the receiver and transmitter.
• Both devices will be compatible with TI's future medium power Qi-compliant transmitters and receivers.

Wireless power evaluation modules

• The bq51025EVM-649 wireless power receiver evaluation kit helps designers evaluate the operation and performance of the bq51025.
• The bq500215EVM-648 wireless power transmitter evaluation module provides all the basic functions of a Qi-compliant, wireless charger pad. The 12-V input, single coil transmitter enables designers to speed time to market.
