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.
