This Hall-effect switch A3163ELT is a monolithic integrated circuit designed to operate continuously over extended temperatures to +85°C. The unipolar switching characteristic makes this device ideal for use with a simple bar or rod magnet. The A3163ELT and A3163EUA are identical except for package.
Each device A3163ELT includes a voltage regulator for operation with supply voltages of 3.5 to 24 volts, reverse-battery protection, quadratic Hallvoltage generator for low offset, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and a constant-current opencollector output, wired internally for true 2-wire operation. Noise radiation is limited by control of the output-current slew rate.
Two package styles of A3163ELT 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 for through-hole mounting; it is also available with lead forming for surface-mount applications (suffix 'UA-TL').
