Introduction
The STEVAL-WBC2TX70 evaluation board, based on the STWBC2 integrated circuit (IC), is designed for wireless power
transmitter applications and allows its user to quickly start their 5 W Qi BPP, 15 W Qi EPP or 70 W STSC wireless charging
projects.
The STWBC2 wireless transmitter IC can deliver the following power transfer levels of inductive wireless power technology:
• Up to 5 W charging power compatible with Qi 1.3 Baseline Power Profile (BPP)
• Up to 15 W charging power compatible with Qi 1.3 Extended Power Profile (EPP)
• Up to 70 W charging power using the STSC Profile
The BPP and EPP are specified by the Wireless Power Consortium’s Qi specification.
The evaluation board is designed to operate with 5-20 V input voltage or with a USB PD power adapter.
Two interfaces are open to the user: UART for monitoring and control via STSW-WBC2STUDIO graphical user interface (GUI)
and SWD JTAG for direct NVM access. Both interfaces are accessible via the STLINK-V3MINIE bridge.
The STEVAL-WBC2TX70 includes several safety mechanisms providing over temperature (OTP), overcurrent (OCP),
overpower (OPP), overvoltage (OVP) and Vin drop protections as well as foreign object detection (FOD) for reliable designs.
