Qi-based wireless power receiver using STWLC68 for Low Power Profile (BPP) applications up to 5W

STEVAL-ISB68RX

 
Overview

The STEVAL-ISB68RX evaluation board with STWLC68 wireless power receiver implements a 5 watt Qi Baseline Power Profile (BPP) application according to Qi specifications 1.2.4. The board functions as a standalone power receiver and provides a fixed output voltage when placed on a suitable wireless power transmitter.

The board also integrates a USB-to-I²C bridge, allowing the user can monitor and control the STWLC68 chip with the STSW-ISB68GUI Graphical User Interface (GUI). The converter may also be used to directly interface with the final application or with other boards based on the same STWLC68 chip.
The STEVAL-ISB68RX includes several safety mechanisms providing overtemperature, overcurrent and overvoltage protection as well as Foreign Object Detection (FOD).
A dedicated connector provides advanced access to STWLC68 chip functionality, including control signals, programmable GPIOs, and analog input for NTC temperature sensor.

Main features

  • Operates in Rx mode as Qi 1.2.4 5W BPP
