Pinning is shown viewed from branded side.
These Hall-effect latches are extremely temperature-stable and stress-
resistant sensors especially suited for operation over extended temperature
ranges to +150°C. Superior high-temperature performance is made possible
through a novel Schmitt trigger circuit that maintains operate and release
point symmetry by compensating for temperature changes in the Hall ele-
ment. Additionally, internal compensation provides magnetic switch points
that become more sensitive with temperature, hence offsetting the usual
degradation of the magnetic field with temperature. The symmetry capability
makes these devices ideal for use in pulse-counting applications where duty
cycle is an important parameter. The four basic devices (3185, 3187, 3188,
and 3189) are identical except for magnetic switch points.
Each device includes on a single silicon chip a voltage regulator, qua-
dratic Hall-voltage generator, temperature compensation circuit, signal
amplifier, Schmitt trigger, and a buffered open-collector output to sink up to
25 mA. The on-board regulator permits operation with supply voltages of 3.8
to 24 volts.
The first character of the part number suffix determines the device
operating temperature range. Suffix ‘E–’ is for -40°C to +85°C, and suffix
‘L–’ is for -40°C to +150°C. Three package styles provide a magnetically
optimized package for most applications. Suffix ‘–LT’ is a miniature SOT89/
TO-243AA transistor package for surface-mount applications; suffix ‘–UA’ is
a three-lead ultra-mini-SIP.

Although sensor location is accurate to three
sigma for a particular design, product improve-
ments may result in small changes to sensor
location.
OPERATION
In operation, the output transistor is OFF until the strength of the mag-
netic field perpendicular to the surface of the chip exceeds the threshold or
operate point (BOP). When the field strength exceeds BOP, the output transis-
tor switches ON and is capable of sinking 25 mA of current.
The output transistor switches OFF when magnetic field reversal results
in a magnetic flux density below the OFF threshold (BRP). This is illustrated
in the transfer characteristics graph (A3187* shown).
Note that the device latches; that is, a south pole of sufficient strength
will turn the device ON. Removal of the south pole will leave the device ON.
The presence of a north pole of sufficient strength is required to turn the
device OFF. Powering up in the absence of a magnetic field (less than BOP
and higher than BRP) will allow an indeterminate output state. The correct
state is warranted after the first excursion beyond BOP or BRP.
