March 24, 2020 by Paul Shepard

The KIT_AURIX_TC21_SC wireless power transmitter evaluation module from Infineon Technologies is a high-performance, easy-to-use development system for the design of automotive in-cabin wireless charging solutions. The system supports all the basic functions of a Qi-compliant, wireless charger for automotive applications.

The three-coil transmitter provides the designer a certified platform that drastically reduces the development time of their end application.  The system supports WPC v1.2.4 receivers up to 15W, as well as all legacy Qi certified receivers.  Smartphones with proprietary fast charge capability are also supported.

Additional features and future standards changes can be supported by the easy-to-upgrade software. The KIT_AURIX_TC21_SC wireless power transmitter evaluation module was developed in cooperation with Spark Connected.
