HVAC Systems

Auto manufacturers (and consumers) continue to demand increased fuel economy, comfort, and performance. Our innovative HVAC solutions help you to deliver on these demands. 

Allegro offers bipolar stepper motor drivers for flap control as well MOSFET gate drivers for higher power HVAC blowers. We also provide a wide array of Hall-based speed, position, and current sensor ICs, providing the necessary feedback signals to optimize system performance and enable rapid detection of fault conditions—which could prevent expensive damage. Patented packaging technology offers high levels of isolation, increasing your system’s safety.
