Wireless Charging Receiver

Higher efficiency, enhanced safety
Wireless Power Receiver

Wireless Charging Transmitter

Qi^®-compliant Transmitter ensures fast and stable single/multi-coil wireless charging for applications from 2.5 W to 15 W

Qi®-Compliant 15 W Multi-Coil Wireless Charger for Mobile Devices

STWBC-MC 15 W 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.

Plug-and-Play Wireless-Charging Kit for Ultra-Compact Chargers for Wearables and IoT Devices

Built around the STWBC-WA wireless charging-transmitter controller, the STEVAL-ISB045V1 kit lets users quickly build ultra-compact chargers up to 2.5W with a space-saving 20mm-diameter coil, for charging small IoT devices and wearables such as smart watches, sports gear, or healthcare equipment.

Getting started is easy, using the PC-based STSW-STWBCGUI software to configure the STWBC-WA and monitor runtime information such as power delivered, bridge frequency, demodulation quality, and protocol status. The kit includes a dongle for running the GUI.
