HOMEPAGE ABOUT ALLEGRO WHAT WE DO What We Do 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. Automotive 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. Our Markets INDUSTRIAL AUTOMOTIVE INFRASTRUCTURE Inspired to innovate, Allegro MicroSystems is redefining the future of sensing and power semiconductor technologies.
