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.
