Heated and ventilated seats must deliver consistent, comfortable temperature control across dozens of heating zones, each requiring precise, self-regulating current control to avoid hot spots or excess power draw. This means precise thermal regulation, efficient power switching, accurate current control, and reliable operation under repeated load cycles.
Vishay’s NTC thermistors provide accurate temperature feedback for seat heating control, while low RDS(on) TrenchFET® Gen IV power MOSFETs efficiently control ventilation fan motors and inductors support filtering and power conversion within the seat electronics.
Behind seat heating and cooling is The DNA of tech.®
