About Allegro MicroSystems
Allegro MicroSystems is a manufacturer specializing in sensor technology and power semiconductors, headquartered in Manchester, New Hampshire (USA). The company develops and manufactures integrated circuits, including Hall-effect sensors, current sensors, angle sensors, gate drivers and regulators for motion control, electrification and safety systems. Manufacturing includes the development and production of semiconductor products based on a 60 V BCD fab process capable of operating up to 175 °C, as well as the manufacture and testing of magnetic devices. Technologies include TMR, GMR and vertical Hall-effect sensing. Customers come from the automotive industry (including electric vehicles and ADAS), industrial and consumer electronics. In addition to its Manchester headquarters, Allegro maintains manufacturing and test sites in Grenoble (France) and Parañaque City (Philippines), as well as a support function in Marlborough, Massachusetts. The company was founded in 1990, has been listed on the Nasdaq since 2020, and holds approximately 1,000 active patents worldwide.
