Industry's only Qi-certified 15W wireless power transmitter

Industrial end equipment such as electronic point-of-sale devices and handheld medical equipment reap the benefits of 15W wireless power. This breakthrough in technology enables connectorless models and reduces overall end-application size by helping eliminate the need for bulky wiring.

Fixed-frequency operation helps achieve the industry’s highest 15W efficiency (84%) as well as reducing EMI. 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 a full 15W with inputs between 15 and 19V and enables lower power operation, such as 5W, with inputs as low as 5V.

The new 15W transmitter joins TI’s proven portfolio of scalable wireless power solutions, which also includes 2.5, 5 and 10W products that provide designers with best-in-class thermal ratings and wide input-voltage and output power ranges, along with customisable sizes and power levels to fit a wide variety of wireless power needs.

Engineers can speed time-to-market and easily evaluate the new device’s features and performance with the bq501210 EVM. The bq501210EVM-756 is available for $149.

Supplied in a 9x9mm VQFN package, the bq501210 transmitter is shipping in volume production now and is priced at $3.75 each in 1,000 unit quantities.
