In the company’s own words
Allegro MicroSystems, Inc.

The company operates as a fabless semiconductor manufacturer with a portfolio exceeding 1,500 products, shipping approximately 2.1 billion units annually to more than 15,000 customers worldwide. Allegro's core offerings span two primary product categories: magnetic sensor integrated circuits and power integrated circuits. The magnetic sensor portfolio represents the broadest range in the industry and includes Hall-effect, giant magnetoresistive, and tunneling magnetoresistive technologies marketed under the XtremeSense brand. Power IC solutions encompass motor drivers, voltage regulators, isolated gate drivers, and power management integrated circuits built on the company's proprietary 120-volt Bipolar-CMOS-DMOS process technology.
Allegro primarily serves automotive and industrial markets, with particular focus on vehicle electrification, advanced driver assistance systems, artificial intelligence data centers, robotics, and energy infrastructure. The company's customer base includes virtually all major global automotive manufacturers, leading tier-one automotive suppliers, and growing numbers of data center and automation customers. Approximately 55 percent of net sales are derived from distributors, with no single end customer exceeding 10 percent of revenues.

Allegro operates research and development centers in the United States, Europe, South America, and Asia, employing approximately 760 engineers dedicated to product development and process technology innovation.
Notable acquisitions include Crocus Technology International Corp. and Heyday Integrated Circuits, which expanded the company's isolated gate driver and tunneling magnetoresistive technology capabilities. The company is a member of the Responsible Business Alliance and maintains supplier codes of conduct addressing labor, safety, and environmental standards throughout its global supply chain.
