About

These include 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). The company can and does combine any two or all three of its product disciplines into a single monolithic chip to deliver powerful system-level solutions. These solutions are sold under Allegro's trademark "ABCD5" (Allegro's BiCMOS, CMOS and DMOS). Allegro's sensors are based on Hall-effect technology, which allows contact-less sensing, (devoid of mechanical w/ear) of either an external magnet or a ferrous object. Specifically, Hall-effect sensors are used for contactless switching, position sensing, speed sensing, linear sensing and gear-tooth sensing. Driver and controller ICs are produced by Allegro are for fractional horsepower dc, stepper and brushless dc motors in the industrial and automotive markets. BCD technology gives Allegro an advantage in higher power applications and allows expansion in existing markets and associated 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. Certification(s):ISO 14001, OHSAS 18001, TS 16949, ISO 9000 ??
