The REF-SHA35WRC2SYS is a part of Infineon’s TRENCHSTOPTM IGBT, gate driver and iMOTIONTM driver reference design kits. It is designed to provide a ready-to-use ceiling fan solution based on the abovementioned technology as well as on the advanced motion control engine (MCE 2.0). The REF-SHA35WRC2SYS is an optimized design for 35 W high voltage ceiling fan applications. It allows fast prototyping and a fast time to market. It is available through regular Infineon distribution partners as well as on Infineon's website. The main features of this board are described in Chapter 1.3 of this document. The remaining sections provide information for customers, enabling them to copy and modify the design for production according to their specific requirements.
