Outline
When the "S" pole of magnet faces the mark surface of the sensor and is closed to sensor(B ≥ Bop),the sensor outputs low level; When "N" pole of magnet is face to sensor's mark surface and clsed to the sensor(B≤ BRP), the sensor outputs high level. When the magnet is far from sensor, (B=0) , the output status is latched and keep constant, in order to change the output status, the reverse polarity magnetic field must be applied on it. The magnet and electric transfer characteristic curve of AH3661 is shown as the figure.
Hall sensor AH3661 is a kind of digital output Hall IC which produced by CMOS Technology. It's bipolar excitation parts. The output signal owns latch function. The sensor chip is produced by CMOS technology, it owns low power consumption, and it has built-in reverse voltage protection, voltage regulators, temperature compensation circuit, Hall-voltage generator, Schmitt trigger,and output driver and other circuit unit etc. Excellent voltage regulator and temperature compensation circuit ensure the sensor stable operates over a wide voltage range and temperature range, and the reverse voltage protection circuit avoids the sensor to be damaged by reverse voltage.
