AH431, designed with Bipolar technology, includes on-chip Hall element voltage generator, a voltage regulator for operation with supply voltages of 3.8 to 60V, temperature compensation circuitry, small-signal amplifier, Schmitt trigger and a switch controlled current source circuit. The sensor is a 2-wire device designed to respond to South poles , the output driver being a current source. The comparator compares the actual magnetic flux with the fixed reference values (switching points). The current source is switched on (high current consumption) or off (low current consumption) . The active offset compensation leads to constant magnetic characteristics over supply voltage and temperature range. 

   AH431 offers a variety of packages, including TO-92S, SOT-23. All packages are RoHS compliant.
