Unipolar Hall Sensor AH441 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 magnet is far away from sensor ， （B≤BRP） the ， sensor outputs high level. When the N pole faces the mark surface，the sensor is no response. Stable Hysteresis(（BH= |BOP- BRP|）ensure the stable sensor’s switch status. The magnet and electric transfer characteristic curve of AH441 is shown as the figure: 南京艾驰电子科技有限公司 NANJING AH ELECTRONIC SCIENCE ＆ TECHNOLOGY CO.,LTD ADD： 南京市江宁区东麒路 33 号国际研发园 B 幢 202-2 室 Room 202-2, Bldg B, 33, Dongqi Road, Nanjing,...

Unipolar Hall Sensor AH441 Pm-il\U Hall sensor AH441 is one of unipolar excitation single-ended digital output Hall IC. The sensor chip has built-in reverse voltage protection, voltage regulators, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open collector output drives circuit unit. 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. Under human being mode,...
