The omnipolar 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-drain output driver, etc.

Produced with CMOS technology, an omnipolar Hall IC is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.

When the magnet (S or N pole) is close to the sensor (|B|≥|BOP|), the sensor outputs a low level; when the magnet is far away from sensor (|B|≤|BRP|), the sensor outputs a high level. Steady Hysteresis (BHX=|BOPX- BRPX|) ensures its stable switch status.
