What We Do

At Allegro MicroSystems, we are passionate about developing intelligent solutions that move the world toward a safer and more sustainable future – while giving our customers a competitive edge. We design and develop sensor ICs and application-specific analog power ICs 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, 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.


Our innovations translate to increased driving range for an electric vehicle, smaller and more reliable power conversion systems, improved safety and efficiency of motor and power management systems and safer and more reliable autonomous driving.

Industrial and Infrastructure

Our technologies enable factory automation, improve reliability to avoid factory downtime, accurately measure current to support increased energy efficiency for high density data centers and green energy applications, and reduce the solution footprint to lower total system cost.
