Digital Bipolar-latch Hall IC 10 Magnetic Behavior South Pole Active When the S pole of the magnet faces the mark surface of the sensor and is close to it (B≥ BOP), the sensor outputs a low level; when the N pole faces the mark surface and is close to it (B≤BRP), the sensor outputs a high level. When the magnet is far away from the sensor (B=0), the output status of the sensor is latched and remains unchanged. In order to change the output status, the applied magnetic field must be opposite polarity. The magnetoelectric conversion characteristics of AH3051 are shown in the figure: Vout...

Digital Bipolar-latch Hall IC North Pole Active When the N pole of the magnet faces the mark surface of the sensor and is close to it (|B|≥|BOP|), the sensor outputs a low level; when the S pole faces the mark surface and is close to it (|B|≥|BRP|), the sensor outputs a high level. When the magnet is far away from the sensor (B=0), the output status of the sensor is latched and remains unchanged. In order to change the output status, the applied magnetic field must be opposite polarity. The magnetoelectric conversion characteristics of AH3051 are shown in the figure: Vout switch to high...
