Allegro MicroSystems [Allegro]

Allegro MicroSystems, Inc. is a leader in developing,manufacturing and marketing high-performance power and Hall-effect sensor integrated circuits.Allegro is headquartered in Worcester, MA with manufacturing plants in New Hampshire, Pennsylvania,Philippines and offices in Scotland, UK, France and Argentina.The company has passed the ISO 9000 quality management system and received quality awards from leading manufacturers worldwide including IECQ manufacturer's approval.Allegro is dedicated to providing value to the customers,offering technically advanced products,achieving growth and profitability,challenging the organization to continuously improve and maintain a positive work environment for the associates.

Allegro is always attaching great importance to technology.Therefore,Allegro has developed total solutions for multiple power ICs and sensing applications.Allegro's products are built with design features including high-current outputs, very wide operating temperature range, reversed power supply, and transient protection, and output short-circuit safety functions.Besides,Allegro has applied  bipolar, CMOS, and DMOS technologies as well as merged technologies such as BiCMOS (bipolar + silicon-gate CMOS), BCD (bipolar + CMOS + DMOS), and DABIC (digital + analog + BiCMOS) into the products to strategically position itself in the analog segment and emphasize application-specific, market-driven products.

Allegro's products include Hall-Effect Sensor ICs, Motor Driver ICs, Power Conversion Devices, Power Interface ICs and Power Management ICs.Allegro is focusing on sensor ICs and power ICs.Allegro's sensor ICs are based on Hall-effect technology, which allows contact-less sensing, (devoid of mechanical wear) of either an external magnet or a ferrous object. Specifically, Hall-effect sensor ICs are used for contactless switching, position sensing, speed sensing, linear sensing and gear-tooth sensing.Allegro's sensor products is mainly used in auto markets including engine, transmission, emissions, suspension, steering, braking, cooling, doors/windows/seats, airbags, and other systems.Furthermore,Allegro is expanding the markets to boat engines and other small engines.

The typical applications of Power ICs in office automation include motor drivers of printers (inkjet for PCs, vending, P-O-S, etc.), scanners, projectors, fax machines, copiers and multifunction peripherals.Driver and controller ICs are designed for fractional horsepower dc, stepper and brushless dc motors in the industrial and automotive markets.With BCD technology,Allegro has an advantage in higher power applications such as large tape drives, automotive blowers, power steering motors, and factory automation.Power Interface ICs are used in industrial and automotive applications such as relays and solenoids, and LED and VF displays. Display drivers include those used in automotive, medical, scales and signs.
