HALL-EFFECT LATCHES
The A3280--, A3281--, and A3283-- Hall-effect latches are extremely
temperature-stable and stress-resistant sensors especially suited for op-
eration over extended temperature ranges to +150°C. Superior high-tem-
perature performance is made possible through dynamic offset cancella-
tion, which reduces the residual offset voltage normally caused by device
overmolding, temperature dependencies, and thermal stress. The three
devices are identical except for magnetic switch points.

Each device includes on a single silicon chip a voltage regulator,
Hall-voltage generator, small-signal amplifier, chopper stabilization,
Schmitt trigger, and a short-circuit protected open-collector output to
sink up to 25 mA. A south pole of sufficient strength will turn the output
on. A north pole is necessary to turn the output off. An on-board regula-
tor permits operation with supply voltages of 4.2 to 24 volts.

Three package styles provide a magnetically optimized package for
most applications. Package type LH is a modified SOT23W surface-
mount package, LT is a miniature SOT89/TO-243AA transistor package
for surface-mount applications; while UA is a three-lead ultra-mini-SIP
for through-hole mounting. Each package type is also available in a lead
(Pb) free version (suffix, –T) , with a 100% matte tin plated leadframe.

FUNCTIONAL DESCRIPTION
Chopper-Stabilized Technique. The Hall element can be
considered as a resistor array similar to a Wheatstone bridge. A
large portion of the offset is a result of the mismatching of these
resistors. These devices use a proprietary dynamic offset
cancellation technique, with an internal high-frequency clock to
reduce the residual offset voltage of the Hall element that is
normally caused by device overmolding, temperature dependen-
cies, and thermal stress. The chopper-stabilizing technique
cancels the mismatching of the resistor circuit by changing the
direction of the current flowing through the Hall plate using
CMOS switches and Hall voltage measurement taps, while
maintaing the Hall-voltage signal that is induced by the external
magnetic flux. The signal is then captured by a sample-and-
hold circuit and further processed using low-offset bipolar
circuitry. This technique produces devices that have an
extremely stable quiescent Hall output voltage, are immune to
thermal stress, and have precise recoverability after temperature
cycling. This technique will also slightly degrade the device
output repeatability. A relatively high sampling frequency is
used in order that faster signals can be processed.

Operation. The output of these devices switches low (turns
on) when a magnetic field perpendicular to the Hall sensor
exceeds the operate point threshold (BOP). After turn-on, the
output is capable of sinking 25 mA and the output voltage is
VOUT(SAT). Note that the device latches; that is, a south pole of
sufficient strength towards the branded surface of the device
will turn the device on; removal of the south pole will leave the
device on. When the magnetic field is reduced below the
release point (BRP), the device output goes high (turns off). The
difference in the magnetic operate and release points is the
hysteresis (Bhys) of the device. This built-in hysteresis allows
clean switching of the output even in the presence of external
mechanical vibration and electrical noise.

Powering up in the absence of a magnetic field (less than

APPLICATIONS INFORMATION
It is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor) between the
supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique.
