Description
The Allegro® A1201, A1202, A1203, and A1204 Hall-effect
bipolar switches are next-generation replacements and
extension of the popular Allegro A3134, A3133, and A3132
bipolar switch product line. Overall, theA120x 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.
TheA120x 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 ±30 V absolute maximum voltage rating for
superior protection in automotive and motor commutation
