Description
The Allegro
"
A1202 and A1203 Hall-effect bipolar switches
are next-generation replacements and extension of the popular
Allegro A3133 and A3132 bipolar switch product line. Overall,
the A120x family, produced with BiCMOS technology, consists
of continuous-time devices that feature fast power-on time
and low-noise operation. Device programming is performed
after packaging, to ensure increased switchpoint accuracy
by eliminating offsets that can be induced by package stress.
Unique Hall element geometries and low-offset amplifiers
help to minimize noise and to reduce the residual offset
voltage normally caused by device overmolding, temperature
excursions, and thermal stress.
The A120x Hall-effect bipolar switches include the following on
a single silicon chip: voltage regulator, Hall-voltage generator,
small-signal amplifier, Schmitt trigger, and NMOS output
transistor. The integrated voltage regulator permits operation
from 3.8 to 24 V. The extensive on-board protection circuitry
makes possible a ?0 V absolute maximum voltage rating for
superior protection in automotive and motor commutation
