Drive

Allegro motor drivers offer industry-leading robustness and safety, thriving in harsh, high voltage environments where competing parts fail.

But while our drivers are tough, they're also quiet. We are experts in helping our customers make their motors run more quietly, efficiently and reliably in automotive, industrial and consumer applications.

And thanks to our decades of experience in motor control, we have developed embedded motion control algorithms that simplify designs while improving your motor performance and time to market.

Featured Products

AMT49406

The AMT49406 is a 3-phase, sensorless, brushless DC (BLDC) motor driver (gate driver) which can operate from 5.5 to 50 V—ideal for ceiling fans, pedestal fans, bathroom exhaust fans and home appliance fans and pumps.
