Allegro Microsystems

Allegro MicroSystems, Inc. provides innovative system-level solutions in the design and manufacture of advanced mixed-signal Hall-effect sensor and analog power ICs. Allegro develops total solutions for many power IC and sensing applications. They provide vertically integrated mixed-signal ICs, adding more components and greater functionality, being the only Hall-effect manufacturer with BiCMOS design capabilities. BCD (Bi-polar, CMOS, DMOS) products offer greater efficiency and control.

The Current Sensor IC families are innovative, monolithic, isolated Hall-effect based devices that provide a fully-integrated solution in industry-leading small-sized packages. As the world leader in Hall-Effect Sensor ICs, Allegro offers a broad line of silicon-based products that serve many high-end applications within automotive and industrial electronics. Allegro's sensor ICs are based on Hall-effect technology, which allows contactless sensing devoid of mechanical wear, sensing either an external magnet or a ferrous object. Power ICs: Allegro also produces motor driver ICs, power management ICs and power interface ICs. Allegro's ICs are used in office automation (particularly printers), industrial, automotive and portable electronics.
