Texas Instruments (TI) (NASDAQ: TXN) today 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.

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

The bq501210 transmitter is shipping in volume production now and is available through the TI store and the company’s authorized distribution network. The bq501210 comes in a 9-mm-by-9-mm very thin quad flat no-lead (VQFN) package and is priced at US$3.75 in 1,000-unit quantities.
