A3295

Chopper Stabilized, Precision Hall Effect Switch for

Consumer and Industrial Applications

FEATURES AND BENEFITS

DESCRIPTION

• Resistant to physical stress

• Superior temperature stability

• Output short-circuit protection

• Operation from unregulated supply

• Reverse battery protection

• Solid-state reliability

The A3295 Hall effect switch is an extremely temperature-

stableandstress-resistantsensorICunipolarswitch,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, temperature dependencies, and thermal stress.

The device is not intended for automotive applications.

• Small package size

Thedeviceincludes,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.

An onboard regulator permits operation with supply voltages

in the range of 3 to 24 volts.

Packages:

3-Pin SIP (suffix UA)

3-Pin SOT23W (suffix LH)

Twopackagestylesprovideamagneticallyoptimizedpackage

for most applications. Type LH is a miniature SOT23W low-

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

ultramini SIP for through-hole mounting. Both packages are

lead (Pb) free, with 100% matte tin plated leadframes.
