WPC 1.1-compliant wireless power controller simplifies development of Qi charging stations | EDN

Texas Instruments has introduced the company’s next-generation wireless power transfer circuit to support the WirelessPower Consortium (WPC) 1.1 specification.
The bq500212A transmitter, which is shipping in volume production, requires one-third fewer components than competitive solutions. The circuit allows designers to quickly take to market Qi-compliant wireless charge pads or stations that can operate from a USB port or 5-V power adapter.
With more Qi charging stations available in the marketplace, consumers of Qi-enabled smartphones, smartwatches and many other ‘enclosed’ portable consumer electronics will be able to keep their batteries charged longer. Products like the Kickstarter-born AGENT Smartwatch are using TI’s bqTESLA wireless power products, including the bq500212A and a bq51050B receiver, to ensure wireless power capability.
“AGENT Smartwatches need to be water resistant, and consumers shouldn’t need to worry about plugging their watches into a charging Adapter day after day,” said Chris Walker, founder of Secret Labs. “TI’s wireless power products give our customers the ability to simply set their AGENT Smartwatch on the included Qi charging pad (or any other Qi-compliant charging pad) from time to time to keep the battery topped off. No wires, no hassle.”
