Fan Control

Efficiently managing airflow for battery and cabin cooling requires compact, reliable fan control solutions, especially in space-constrained 48V and 12V systems.

Allegro provides highly integrated half-bridge and BLDC motor controllers that simplify design and reduce footprint. Our QuietMotion drivers minimize audible noise and vibration. To enable quiet, efficient, and compact fan designs that contribute to overall thermal system effectiveness and passenger comfort without adding unnecessary complexity or noise.
