Beschreibung

The STEVAL-ISB044V1 evaluation kit has been designed for devices, such assmartphones 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-effectivehalf-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 whichgive runtime information, such as the power delivered, the regulation error or theprotocol status as well as parameter tuning.
