◆ Outline

The AH3051 is a high sensitivity digital bipolar-latch Hall IC with single output. It has good temperature stability and latch function. The AH3051 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 AH3051, produced with bipolar technology, is more stable and reliable in some special application. It is available in three package types: SOT-23-3L (Type M), SOT-89 (Type S), and TO-92 (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
