Introduction
The STEVAL-WBC86TX evaluation board, based on the STWBC86, is designed for wireless power transmitter applications and
allows its users to quickly start their 5 W Qi BPP wireless charging projects.
The STWBC86 wireless transmitter IC can deliver up to 15 W (coil dependent), however this reference design document is
limited to only provide sufficient information to develop a project for up to 5 W charging compatible with Qi 1.2.4 Baseline Power
Profile (BPP) power transfer by Wireless Power Consortium’s inductive wireless power technology.
The integrated circuit requires only a few external components and can work with 5-20 V input voltage.
Using an on-board USB-to-I2C bridge, the user can monitor and control the STWBC86 using the STSW-WPSTUDIO graphical
user interface (GUI).
The STEVAL-WBC86TX includes several safety mechanisms providing overtemperature (OTP), overcurrent (OCP), and
overvoltage (OVP) protections as well as foreign object detection (FOD) for reliable designs.
