SENSITIVE 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

temperature and supply voltage changes. The unipolar switching

characteristic makes these devices ideal for use with a simple bar or rod

magnet. The four basic devices (3141, 3142, 3143, and 3144) are

identical except for magnetic switch points.

Each device includes a voltage regulator for operation with supply

voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic

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 A3141– and A3142– are im-

proved replacements for the UGN/UGS3140–; the A3144– is the

improved replacement for the UGN/UGS3120–.

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 ‘–UA’ is a three-lead

ultra-mini-SIP.
