Description
The STEVAL-ISB044V1 evaluation kit has been designed for devices, such as smartphones or tablets, requiring high power levels. It supports wireless battery charging up to 15 W. The embedded STWBC-EP digital controller transmitter is based on a cost-effective half-bridge topology providing external interfaces via UART and I²C. The kit also includes STWBC-EP firmware, a graphical interface for debug, schematics, layout files and bill of materials. There are specific tools for the STEVAL-ISB044V1 available on www.st.com which give runtime information, such as the power delivered, the regulation error or the protocol status as well as parameter tuning.
Features
◦STWBC-EP digital controller◦15 W output power◦Qi MP-A10 reference design◦WPC Qi1.2.3 standard compliant◦Robust demodulation algorithm, with triple path (V, I, f)◦Foreign object detection (FOD)◦Accurate power control
◦Active presence detection◦UART protocol to control and monitor the system◦Complete reference design (evaluation board, IC, firmware and tools)◦2-layer PCB for easy design◦Flash memory-based◦RoHS compliant
