Allegro specializes in magnetic sensor ICs and power ICs used in critical applications including electric vehicle powertrains, advanced driver assistance systems (ADAS), electrified propulsion systems, battery management, and industrial automation. The company's product portfolio encompasses current sensors, position sensors, speed sensors, and motor driver ICs that enable precise control and monitoring in automotive and industrial equipment.
