HALL-EFFECT SWITCHES
FOR HIGH-TEMPERATURE OPERATION
These Hall-effect switches are monolithic integrated circuits with
tighter magnetic specifications, designed to operate continuously over
extended temperatures to +150°C, and are more stable with both tem-
perature and supply voltage changes. The unipolar switching character-
istic makes these devices ideal for use with a simple bar or rod magnet.
The three basic devices (A3121, A3122, and A3123) are identical except
for magnetic switch points.
Each device includes a voltage regulator for operation with supply
voltages of 4.5 volts to 24 volts, reverse battery protection diode, qua-
dratic Hall-voltage generator, temperature compensation circuitry, small-
signal amplifier, Schmitt trigger, and an open-collector output to sink up
to 25 mA. With suitable output pull up, they can be used with bipolar or
CMOS logic circuits. The A3121 is an improved replacement for the
UGx3113 and UGx3119.

The first character of the part number suffix determines the device
operating temperature range. Suffix ‘E–’ is for the automotive and
industrial temperature range of -40°C to +85°C. Suffix ‘L–’ is for the
automotive and military temperature range of -40°C to +150°C. Two
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.

OPERATION
OPERATION
ELEMENT LOCATIONS
The output of these devices (pin 3) switches low when the mag-
netic field at the Hall element exceeds the operate point threshold (BOP).
At this point, the output voltage is VOUT(SAT). When the magnetic field
is reduced to below the release point threshold (BRP), the device output
goes high. The difference in the magnetic operate and release points is
called the hysteresis (Bhys) of the device. This built-in hysteresis allows
clean switching of the output even in the presence of external mechani-
cal vibration and electrical noise.
