Texas Instruments joins the Alliance for Wireless Power

Texas Instruments has announced that it is joining the Alliance for Wireless Power (A4WP) while at the same time it continues to support the Wireless Power Consortium's Qi standard. The A4WP is a group made up of electronics firms like Samsung and Qualcomm and has issued an official specification based on magnetic resonance. Using this method, different devices with different power requirements, like a smartphone and a tablet, can be charged together at the same time.

TI says that the WPC Qi is the "standard for wireless power today" and noted that the trend is toward "loosely coupled technologies" which the WPC and the A4WP are taking a look at. The latter organization was formed in April. The company says that working with both groups will allow it to remain the leader in wireless power. To that end the company says it will continue to develop new bqTESLA wireless receivers and transmitter integrated circuits that meet the specs of the WPC while working on products that support the specs of the A4WP.

The Qi standard is behind the wireless charging available for the new Nokia Lumia Windows Phone 8 models and the Google Nexus 4. The latter will use a wireless charging orb which has not yet been released to the market.

Press Release

DALLAS, Dec. 7, 2012 /PRNewswire/ — Texas Instruments Incorporated (TI) today announced it has joined the Alliance for Wireless Power (A4WP). TI will continue to develop new bqTESLA™ wireless power receiver and transmitter integrated circuits that comply with existing and future versions of the Wireless Power Consortium (WPC) Qi standard, and also create products that support the A4WP magnetic resonance specification.

“TI is actively bringing advanced wireless power capabilities to the market,” said Sami Kiriaki, senior vice president of TI Power Management. “The WPC Qi specification is clearly the standard for wireless power today, and there is an emerging trend toward loosely coupled technologies – something both WPC and A4WP are exploring. We believe that working closely with both initiatives will help us continue to lead in wireless power.”

Organized in April, A4WP is a group of electronics companies, including Samsung, Qualcomm and others, focused on advancing the field of wireless power by delivering a specification that permits spatial freedom. The group officially released its A4WP specification, which is based on loosely coupled magnetic resonance technology, to simultaneously charge smartphones and other portable electronics with different power requirements.

TI is making wireless power a reality

Wireless power is an emerging technology that creates a better charging experience for consumers, just as Wi-Fi replaced the need to use an Ethernet cable for Internet connectivity. TI’s advanced receiver and transmitter integrated circuits, such as the recently announced bq51050B single-chip wireless power receiver with integrated charger and bq500410A 3-coil transmitter, are making wireless power a reality. As the leading provider of power management ICs, including battery management and power supply technology, TI relies on its power design expertise to drive innovations in wireless charging.
