Unipolar High Sensitivity Hall Effect IC, Hall IC, Hall Sensor, Hall Switch, Switch,
AH3132 is an unipolar high sensitivity Hall effect magnetic sensor which is made by BiCMOS technology (Hall effect digital intergrated circuit. It includes voltage regulators, Hall voltage generator, signal amplifier, Schmitt trigger , temperature compensation circuit, and open collector output driver circuit etc. It's suitable for working in unipolar magnetic field, and it's extensively used in different kinds of electromechanical integration fields.
When a "S" pole magnetic field is closing to the front of the circuit, the output of the circuit changes from high level to low level, if the field is far from the circuit, the output changes from low level to high level.
