Wireless power chip gør det lettere at udvikle Qi ladestationer

Texas Instruements 2. generations WPC 1.1-compliant power controller kræver en tredjedel mindre eksterne komponenter og gør det muligt for wireless ladestationer at operere fra en USB port.

Building on its industry-leading power management portfolio, Texas Instruments (TI) has introduced its next-generation wireless power transfer circuit to support the Wireless Power 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, says 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.
