Description
The Allegro
"
A1205 Hall-effect bipolar switch is a next-
generation replacement and extension of the popular Allegro
A3134 bipolar switch. The A1205 has identical specifications
as the A1201 but is recommended for applications that require
pulsing V
CC
to conserve power. For standard applications,
where V
CC
is constant, please refer to the A1201 through
A1204 devices.
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
