Data Sheet 27621.31a Suffix 'UA' Pinning (ultra-mini SIP) 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 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 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 pensation circuitry, small-signal amplifier, Schmitt trigger, and a constant-current opencollector...
