Flap Control

Accurately directing airflow within the HVAC and thermal systems requires quiet and precise control of flaps.

Allegro Stepper motor drivers provide easy open-loop position with low noise due to high-resolution microstepping. They also include diagnostics like open/short load detection to enhance safety and performance. To enable silent and accurate airflow management, contributing to both passenger comfort and the overall efficiency of the thermal system.
