The AH3144 is a high sensitivity digital unipolar Hall IC with single output.
The AH3144 Hall-effect sensor includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open collector output driver, etc. The integrated voltage regulator and temperature compensation circuit ensure that the sensor works stably in a wide voltage and temperature range. The reverse voltage protection circuit prevents the sensor from being damaged by reverse voltage.
The AH3144, produced with bipolar technology, is more stable and reliable. It is available in three package types: SOT-23-3L (Type M), SOT-89 (Type S), and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
