Description
The A3282 Hall-effect sensor IC is a temperature stable,
stress-resistant latch. Superior high-temperature performance
is made possible through an Allegro
?/DIV>
patented dynamic
offset cancellation that utilizes chopper-stabilization. This
method reduces the offset voltage normally caused by device
overmolding, temperature dependencies, and thermal stress.
The A3282 complements the current Allegro family of chopper-
stabilized latching devices.
The A3282 includes 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.
This device requires the presence of both south and north
polarity magnetic fields for operation. In the presence of a
south polarity field of sufficient strength, the device output
latches on, and only switches off when a north polarity field
of sufficient strength is present.
