STMicroelectronics Intros Wireless Charging Kit for Wearables, IoT Devices

STMicroelectronics has announced its STEVAL-ISB045V1 plug-and-play wireless battery-charger development kit, designed to let users build compact chargers at up to 2.5W with a 20-millimeter-diameter coil. The device is designed for charging small Internet of Things (IoT) devices and wearables, such as smart watches, sports gear and health-care equipment.

Built around the STWBC-WA wireless charging-transmitter controller, the kit comprises a charging base unit containing a transmitter board with the coil already connected and ready to use. PC-based STSW-STWBCGUI software can 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, while the supporting ecosystem includes certified reference boards, software and detailed documentation.

The STWBC-WA controller chip contains integrated drivers and natively supports full- or half-bridge topologies for powering the antenna. The half-bridge option allows charging up to 1W with a smaller-diameter coil for a more compact form factor. The chip supports all standard wireless-charging features, including foreign object detection (FOD) and active presence detection for safe charging, and uses digital feedback to adapt the transmitted power according to load conditions. Two firmware options give users the choice of a turnkey solution or customizing the application using APIs to access on-chip peripherals, including an ADC, a UART and GPIOs.

The STEVAL-ISB045V1 kit is available now for $42. STWBC-WA transmitter controller ICs are currently in production, priced from $2.82 in VFQFPN32 package for orders of 1,000 pieces.
