HALL-EFFECT SWITCH
FOR 2-WIRE APPLICATIONS
This Hall-effect switch is a monolithic integrated circuit designed to
operate continuously over extended temperatures to +85°C. The unipo-
lar switching characteristic makes this device ideal for use with a simple
bar or rod magnet. The A3161ELT and A3161EUA are identical except
for package.
Each device includes a voltage regulator for operation with supply
voltages of 3.5 to 25 volts, reverse battery protection diode, quadratic
Hall-voltage generator, temperature compensation circuitry, small-signal
amplifier, Schmitt trigger, and a constant-current open-collector output.
Noise radiation is limited by control of the output current slew rate.
Two package styles provide a magnetically optimized package for
most applications. Suffix ‘LT’ is a miniature SOT-89/TO-243AA
transistor package for surface-mount applications; suffix ‘UA’ is a three-
lead ultra-mini SIP for through-hole mounting.
