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. 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 ‘–U’ is a three-lead

plastic mini-SIP while suffix ‘–UA’ is a three-lead ultra-mini-SIP.
