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.
