Description

The A3282 Hall-effect sensor is a temperature stable, stress-

resistant latch. Superior high-temperature performance

is made possible through an Allegro

廬

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 sensors.

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.

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)
