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 A3163ELT and A3163EUA are identical except

for package.

Suffix 'UA' Pinning

(ultra-mini SIP)

Each device includes a voltage regulator for operation with supply

voltages of 3.5 to 24 volts, reverse-battery protection, quadratic Hall-

voltage generator for low offset, temperature compensation circuitry,

small-signal amplifier, Schmitt trigger, and a constant-current open-

collector output, wired internally for true 2-wire operation. 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 SOT89/TO-243AA transis-

tor package for surface-mount applications; suffix ‘UA’ is a three-lead

ultra-mini SIP for through-hole mounting; it is also available with lead

forming for surface-mount applications (suffix 'UA-TL').
