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.
