The bipolar 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.

Produced with bipolar technology, a bipolar Hall IC 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-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.

North Pole Active

When the N pole of the magnet faces the mark surface of the sensor and is close to it (|B|≥|BOP|), the sensor outputs a low level; when the S pole faces the mark surface and is close to it (|B|≥|BRP|), the sensor outputs a high level. When the magnet is far away from the sensor (B=0), the output status of the sensor is latched and remains unchanged. In order to change the output status, the applied magnetic field must be opposite polarity. 

Note: the SOT-23-3L package is north pole active, and the SOT89 and TO92UA package are south pole active.
