Outline

AH3663 is a kind of high sensitivity omnipolar micropower Hall sensor. The special designing circuit enable the sensor has omnipolar (no “S” or “N” pole) magnetic field excitation function, excellendt positive and negative switch symmetry, and bitty average powr consumption current. When the magnet (no “S” or “N” pole) is closed to sensor（︱B︱≥︱Bop︱），the sensor outputs low level; when the magnet is far away from sensor ︱B︱≤︱Brp︱）, the sensor outputs high level.
