Automotive : Body Systems : Brushless DC Fan Commutation

The increased use of electronics in vehicles creates more heat that has to be dissipated. This factor together with increased passenger comfort are driving the demand for small, high performance and quiet operating fans.

Next to HVAC blowers fans are used in seat ventilation. Small fans built into the seat and backrest provide the occupant with an optimized climate. Melexis driver ICs ensure quiet, efficient and intelligent control of the fans.
