\"image001\"<\/a>October 8<\/b>-The STMicroelectronics\u00a0STWBC-MC<\/b>\u00a015W wireless battery-charger transmitter can control multiple charging coils, making charging less dependent on the precise position of the battery-powered device.<\/u><\/u><\/p>\n

Compliant with the latest Qi\u00ae<\/sup>\u00a01.2.4 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.<\/u><\/u><\/p>\n

To ensure fast and stable charging for all types of devices, the STWBC-MC monitors coil current and voltage. By integrating a digital DC-DC controller, it delivers the required power to the coil at a fixed frequency and so minimizes interference with other systems inside smartphones and tablets. Given the EU\u2019s intention to extend the scope of the Radio Equipment Directive (RED) to include wireless-charging transmitters, and restrict H-field emissions above 145kHz to -5dBm, the STWBC-MC\u2019s low-EMI design eases compliance.<\/u><\/u><\/p>\n

ST\u2019s patented triple-path modulation technique for communication between the transmitter and receiver increases noise immunity and the IC\u2019s low standby consumption minimizes wasted energy when not charging.<\/u><\/u><\/p>\n

Users can start development quickly using the STEVAL-ISB047V1 evaluation kit for the STWBC-MC and the STSW-STWBCGUI graphical user interface for ST\u2019s STWBC transmitter ICs. The GUI can be used to download the STSW-ISB047FW dedicated firmware for the STWBC-MC, and to monitor performance and fine-tune parameters.<\/u><\/u><\/p>\n

The STWBC-MC is in production, priced from $3.375 for orders of 1000 pieces. The STEVAL-ISB047V1 is available now from\u00a0st.com\u00a0or distributors, for $170.<\/u><\/u><\/p>\n
