STEVAL-ISB68WA Data brief Qi-based wireless power receiver reference design for wearable applications up to 2.5 W using STWLC68 Features Based on STWLC68 wireless power receiver Designed according to Qi 1.2.4 specifications Constant 5 V output voltage (default setting) Up to 2.5 W output power Foreign Object Detection (FOD) supported 400 kHz IC interface for communication with host system Compact 10x10 mm application area Complete kit includes receiver board, USB-to-IC bridge dongle and GUI RoHS compliant Description The STEVAL-ISB68WA is a reference design for wearable applications based on the STWLC68 wireless power receiver. The kit includes a receiver board with a small 15 mm diameter receiving coil and provides a constant output voltage with 2.5 W maximum output power. The board supports Foreign Object Detection (FOD) for safe operation and is ready for immediate use when placed on a suitable wireless power transmitter. An on-board LED indicates connection with the transmitter succeeds and enabled output voltage, and a programmable interrupt output is available to inform the host system in user applications. Product summary The complete application is confined in a 10x10 mm PCB area and the layout is designed to facilitate probing and user customization. reference design based on STWLC68 wireless STEVAL- A free STSW-ISB68GUI Graphic User Interface (GUI) is provided to monitor and power receiver for ISB68WA configure the receiver on your PC using the USB-to-IC dongle included in the kit. wearable applications Qi-compliant inductive wireless power receiver STWLC68 for 5W applications GUI for developing applications using the STSW- STWLC68 wireless ISB68GUI power receiver Wireless Chargers Applications Wearable DB4110 - Rev 2 - January 2020 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-ISB68WA Layout of components 1 Layout of components Figure 1. receiver board silk screens - top and bottom U1: STWLC68 wireless power receiver Figure 2.
