Electronic pumps and fans across the vehicle's cooling circuits — blower and vent control and engine cooling — must run efficiently at variable speed for years, often in locations directly exposed to road debris, heat, and vibration. This dictates efficient motor control, accurate current measurement, low electromagnetic interference, and reliable component operation at elevated temperatures.
Vishay's power MOSFETs and power ICs deliver efficient, variable speed motor drive for pumps and fans, while shunt resistors offer current feedback, and inductors and capacitors handle filtering. Our NTC thermistors provide the temperature feedback that speed control algorithms depend on. AEC-Q certifications confirm our products perform reliably in the harsh underhood environment.
Behind electronic pumps and fans is The DNA of tech.®
