STMicroelectronics STWLC38 | Demoboard STDES-WLC38TWS

Description

The STDES-WLC38TWS reference design is based on STWLC38. It is designed for wireless power receiver application and it allows you to quickly start your 2.5 W Qi-BPP compatible wireless charging receiver projects.This reference design document provides sufficient information to develop a project for up to 2.5 W charging using baseline power profile (BPP).Through the I²C interface you can access and modify different configuration parameters, tailoring the operation of the device to the needs of custom applications. Using an on-board USB-to-I²C bridge, you can monitor and control the STWLC38 thanks to the STSW-WPSTUDIO graphical user interface (GUI).
