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 PTC heating elements and NTC thermistors provide the self-regulating heat and accurate temperature feedback seat heating systems demand, while our low RDS(on) power MOSFETs and power ICs switch and control fan-driven seat cooling, and inductors and capacitors ensure clean power delivery. Our Power Metal Strip® shunts are used for current measurement, completing the thermal control loop with the NTC thermistors.
Behind seat heating and cooling is The DNA of tech.®
