Description
The A3241 and A3242 integrated circuits are unipolar Hall-
effect switches with digital outputs. These devices are suited
for operation over extended temperature ranges, up to +150°C.
Superior high-temperature performance is made possible
through an Allegro
which reduces the residual offset voltage normally caused
by device overmolding, temperature excursions, and thermal
stress.
The A3241 and A3242 Hall-effect switches include the
following on a single silicon chip: voltage regulator, Hall-
voltage generator, small-signal amplifier, chopper stabilization,
Schmitt trigger, and a short circuit protected open-drain output.
Advanced BiCMOS wafer fabrication processing is used to
take advantage of low-voltage requirements, component
matching, very low input-offset errors, and small component
geometries.
The integrated voltage regulator permits operation from 3.6 to
24 V. The unipolar family members operate with a sufficient
south polarity field only, turning off in the absence of such a
south polarity field.
