Beschreibung

The following describes the operation of the STEVAL-ISB027V1 Qi A11 wireless power transmitter evaluation board. The STEVAL-ISB027V1 is a certified reference design based on the Qi A11 wireless power consortium (WPC) standard version 1.1.2, and supports FOD (foreign object detection).The transmitter is compatible with all Qi-compatible receivers, such as those already available in Qi-enabled mobile phones. Receivers with both resistive or capacitive modulation are supported.In accordance with the Qi A11 topology, the STEVAL-ISB027V1 supports a 5 V input and a full bridge stage with both frequency and duty cycle control. The STEVAL-ISB027V1 features the STWBC controller, which integrates all the functions required to drive and monitor the transmitter.STWBC supports UART connectivity to a PC and thanks to the STEVAL-ISB027V1 graphical interface, it is possible to monitor the behavior of the transmitter in real-time.The STEVAL-ISB027V1 reference design provides a complete kit which includes the STWBC, firmware, layout, graphical interfaces and tools. The layout is based on a costeffective 2-layer PCB.This user manual explains the STEVAL-ISB027V1 hardware and software installation, as well as details on the evaluation of the board and the GUI interface.
