Allegro MicroSystems

We design and develop sensor ICs,  application-specific analog power ICs  and photonics components that meet the needs of the most demanding applications. As the number one supplier of magnetic sensor IC solutions and a leading supplier of power ICs and photonics, we have developed a track record of applying innovative circuit design, process and packaging technologies to deliver highly reliable, high-performance solutions that precisely measure motion, speed, position and current. 

Allegro is at the heart of systems that sense, regulate and drive a variety of mechanical systems. This includes sensing angular or linear position, driving an electric motor or actuator, and regulating the power applied to sensing and driving circuits so they operate safely and efficiently.   

These capabilities are based on fundamental technical advances we have made in the field of magnetic sensor and power ICs.
