Texas Instruments now offers the industry’s first WPC v1.2 Qi-certified, 15-W wireless power transmitter. Intended to deliver high-power wireless charging to industrial systems (e.g., hand-held medical devices), the bq501210 enables 84% system efficiency with significantly less thermal dissipation.
The bq501210’s features, benefits, and specs:
- Fixed-frequency operation enables 15-W efficiency and reduces electromagnetic interference (EMI).
- Fast-charging capability enables the transfer of up to 10 W to compatible receivers, including currently available fast-charging devices.
- The High-Voltage Dedicated Charging Port (HVDCP) protocol negotiates with capable AC/DC wall adapters to adjust the input voltage.
The bq501210 transmitter is shipping in volume production. It comes in a 9 mm × 9 mm VQFN package and costs $3.75 in 1,000-unit quantities. An evaluation module (bq501210EVM-756) is available for $149.
