A3282

Chopper-Stabilized Hall Effect Latch

The A3282 Hall-effect sensor is a temperature stable, stress-resistant latch. Supe-

rior high-temperature performance is made possible through an Allegro^®pat-

ented 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.

Package LH, 3-pin Surface Mount

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 fabrica-

tion 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 suf-

ﬁcient strength is present.

Package UA, 3-pin SIP

The A3282 is rated for operation between the ambient temperatures –40°C and

85°C for the E temperature range, and –40°C to 150°C for the L temperature

range. The two package styles available provide magnetically optimized solutions

for most applications. Package LH is an SOT23W, a miniature low-proﬁle sur-

face-mount package, while package UA is a three-lead ultramini SIP for through-

hole mounting. Each package is available in a lead (Pb) free version, with 100%

matte tin plated leadframes.
