BARCELONA, Spain, Feb. 27, 2014

BARCELONA, Spain, Feb. 27, 2014 /PRNewswire/ --Improving the mobile charging
experience, Texas Instruments (TI) (NASDAQ: TXN) today announced it is
shipping in volume production the industry's smallest, most efficient wireless
power receiver to support both the Wireless Power Consortium's (WPC) Qi 1.1
and Power Matters Alliance (PMA) specifications. The new bq51221
inductor-less, 5-watt receiver's high efficiency and programmable output
reduces power loss by as much as 50 percent compared to existing receiver
solutions, allowing consumers to more efficiently and quickly charge their
mobile phones, headsets and power banks from a Qi or PMA charging station. To
order samples and a development kit, visit: www.ti.com/bq51221-pr.

Features and benefits of bq51221:

  oDual-mode, 5-watt receiver: Compliant with Qi 1.1 and PMA communication
    and control.
  oHigh efficiency for fast charge time: Achieves up to 96 percent power
    efficiency, and the device's adjustable output voltage helps reduce power
    loss by as much as 50 percent.
  oIndustry's smallest, thinnest solution: 3.6-mm by 2.9-mm by 0.5-mm
    single-chip wireless power receiver achieves a solution size of 75 mm^2
    without the need for an inductor.

In addition to the dual-mode receiver, TI also introduced its bq51010B
next-generation Qi 1.1-compliant receiver with an integrated 7-V regulated
supply and foreign object detection. The single-chip receiver, also shipping
in volume production, achieves 93 percent power efficiency and ensures the
lowest possible power dissipation when charging a Qi-compliant smartphone.
