Room Air conditioning systems must be highly energy-efficient and reliable - to help saving on energy and maintenance costs – and provide an accurate temperature control and silent operation for building occupant’s enhanced comfort.

We provide a large selection of IGBTs, power MOSFETS and intelligent power modules (IPM) as well as integrated motor drivers and STM32 microcontrollers to build high-efficient motor control solutions as well as a wide selection of MEMS environmental sensors and wireless connectivity solutions to enable building more connected and efficient Air conditioning solutions.

In addition we provide a comprehensive set of HW and SW evaluation and development tools and reference designs to help compress time to market.
