Qi-certified 15-W Wireless Power Transmitter

Nov. 9, 2016
Texas Instruments (TI) introduced the industry's first Wireless Power Consortium (WPC) v1.2 Qi-certified 15-W wireless power transmitter.

Texas Instruments (TI) introduced the industry's first Wireless Power Consortium (WPC) v1.2 Qi-certified 15-W wireless power transmitter. The bq501210 enables 84 percent system efficiency with significantly less thermal dissipation than traditional wireless power devices. The transmitter supports multiple fast-charging protocols and offers an array of flexible and customizable features such as personal electronics, medical and space-constrained industrial applications.

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

Features and benefits of the bq501210

  • System efficiency at 84 percent: Fixed-frequency operation helps achieve the industry's highest 15-W efficiency as well as reducing electromagnetic interference (EMI).
  • Fast-charging capability: Fast-charge negotiation with mobile devices enables the transfer of up to 10 W to compatible receivers, including existing fast-charging devices on the market.
  • Wide-voltage aptitude: 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 15 W with inputs between 15 V and 19 V, and enables lower power operation, such as 5 W, with inputs as low as 5 V.
Engineers can speed time to market and easily evaluate the new device's features and performance with the bq501210 evaluation module (EVM). The bq501210EVM-756 is available for $
149.
