HAL576  
4.4. HAL576  
Applications  
The HAL576 is a medium sensitive unipolar switching  
sensor (see Fig. 4–13).  
The HAL576 is designed for applications with one  
magnetic polarity and weak magnetic amplitudes at  
the sensor position such as:  
The sensor turns to high current consumption with the  
magnetic south pole on the branded side of the pack-  
age and turns to low current consumption if the mag-  
netic field is removed. It does not respond to the mag-  
netic north pole on the branded side.  
– applications with large airgap or weak magnets,  
– solid state switches,  
– contactless solutions to replace micro switches,  
– position and end point detection, and  
– rotating speed measurement.  
For correct functioning in the application, the sensor  
requires only the magnetic south pole on the branded  
side of the package.

The hysteresis is the difference between the switching points BHYS = BON BOFF  
The magnetic offset is the mean value of the switching points BOFFSET = (BON + BOFF) / 2
