About Allegro MicroSystems
Founded in 1990 and headquartered in Manchester, New Hampshire, Allegro MicroSystems focuses exclusively on motion control, power efficiency, and sensing — a specialization that gives it deep application expertise in automotive electrification and industrial motor drive systems. Allegro went public in 2020 and continues to expand its product portfolio for xEV, ADAS, and clean-energy applications.
Allegro's flagship product lines include ACS current sensor ICs (Hall-effect based, offering galvanic isolation and high bandwidth), magnetic angle and linear position sensors for electric power steering and pedal sensing, and gate driver ICs for IGBT and SiC MOSFET power stages. The company also leads in automotive-qualified LED driver ICs for matrix headlamps and interior ambient lighting.
On Octatronics, source Allegro components by function, AEC-Q100 qualification grade, package type, and output interface. Submit RFQs for ACS712, ACS758, A1332, and other high-demand Allegro parts with stock visibility and lead-time estimates.
