A3290 and A3291

Chopper-Stabilized, Precision Hall-Effect Latches for

Consumer and Industrial Applications

FEATURES AND BENEFITS

DESCRIPTION

• Symmetrical switchpoints

• Resistant to physical stress

• Superior temperature stability

• Output short-circuit protection

• Operation from unregulated supply

• Reverse battery protection

• Solid-state reliability

The A3290 and A3291 Hall-effect latches are extremely

temperature-stable and stress-resistant sensor ICs, especially

suited for operation over extended temperature ranges (up

to 125°C). Superior high-temperature performance is made

possible through dynamic offset cancellation, which reduces

the residual offset voltage normally caused by device package

overmolding,temperaturedependencies,andthermalstress.The

twodevicesareidenticalexceptfortheirmagneticswitchpoints.

They are not intended for automotive applications.

• Small package size

Bothdevicesinclude,onasinglesiliconchip,avoltageregulator,

a Hall voltage generator, a small-signal amplifier, chopper

stabilization, a Schmitt trigger, and a short-circuit protected

open-drainoutputtosinkupto25mA.Asouthpolaritymagnetic

field of sufficient strength is required to turn the output on. A

north polarity field of sufficient strength is necessary to turn

the output off. An onboard regulator permits operation with

supply voltages in the range of 3 to 24 V.

Packages:

3-Pin SOT23W

(suffix LH)

3-Pin SIP (suffix UA)

Two package styles provide a magnetically optimized package

for most applications: type LH is a miniature SOT23W low-

profile surface-mount package, and type UA is a three-pin

ultramini SIP for through-hole mounting. Both packages are

lead (Pb) free with 100% matte-tin leadframe plating.
