Description

The STEVAL-ISB047V1 wireless battery charger TX evaluation kit consists of the

STEVAL-ISB047V1T evaluation board and STEVAL-WBCDNGV1 USB-UART

dongle. The kit is designed for charging devices such as smartphones or tablets

where high power levels are required.

The evaluation board supports wireless battery charging of Qi-compliant devices up

to 15 W. It also supports proprietary fast charging modes up to 10 W.

The STEVAL-ISB047V1 transmitter is based on the STWBC-MC and features a cost-

effective half bridge topology, offering external interface via UART.

The STEVAL-ISB047V1 evaluation kit is a full solution, complete with boards,

firmware, a GUI for debugging, schematics, layout files and bill of materials.

Tools for STEVAL-ISB047V1 are available on www.st.com, and allow users to access

runtime information such as power delivered, regulation error and protocol status.

Parameters can also be adjusted with these tools.
