Get Started

Heating, Ventilation and Air Conditioning (HVAC) systems must be highly energy-efficient and reliable to help save on energy and maintenance costs. But they also need to provide an accurate temperature control and silent operation for the building occupant's enhanced comfort.

A central HVAC system comprises a large number of motor control sub-systems to drive fans and compressors and a variety of environmental sensors.

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 highly-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 central HVAC solutions.

In addition we provide a comprehensive set of hardware and software evaluation and development tools, reference designs to help reduce your time to market.
