Wireless power transmitter is Qi-certified

Claimed to be the industry’s first Wireless Power Consortium (WPC) v1.2 Qi-certified 15W wireless power transmitter, the bq501210 has been introduced by Texas Instruments.

It enables 84% system efficiency with significantly less thermal dissipation than traditional wireless power devices, says the company. The transmitter supports multiple fast-charging protocols and has customisable features for personal electronics, medical and space-constrained industrial applications.

Target applications are industrial end-equipment such as electronic point-of-sale devices and handheld medical equipment, which can be reduced in size with the absence of bulky wiring.

Fixed-frequency operation helps achieve the industry’s highest 15-W efficiency as well as reducing EMI, claims the company. The fast-charge negotiation with mobile devices enables the transfer of up to 10W to compatible receivers, including existing fast-charging devices on the market.

The high-voltage dedicated charging port (HVDCP) protocol negotiates with capable AC/DC wall adapters to adjust the input voltage. The rail control output provides power to deliver 15W with inputs between 15 and 19V, and enables lower power operation, such as 5W, with inputs as low as 5V.

An bq501210 evaluation module is available for the 9.0 x 9.0mm VQFN (very think quad flat no-lead) package.
