Advanced Qi® -Compliant Transmitter Ensures Fast 15W Multi-Coil Wireless Charging

29.10. 2018 | News

The STMicroelectronics STWBC-MC 15W wireless battery-charger transmitter can control multiple charging coils, making charging less dependent on the precise position of the battery-powered device.

Compliant with the latest Qi® 1.2.4 specification, the STWBC-MC is the first transmitter specifically designed to support the Qi MP-A15 EPP (Extended Power Profile) topology. In addition to detecting a valid receiver and selecting the most efficient coil for power transfer, it ensures extended Foreign Object Detection (FOD) through bi-directional communication with the receiver. The STWBC-MC also supports the proprietary wireless fast-charge extensions of leading smartphone manufacturers.

Users can start development quickly using the STEVAL-ISB047V1 evaluation kit for the STWBC-MC and the STSW-STWBCGUI graphical user interface for ST’s STWBC transmitter ICs (more info).
