HAL574  
4.2. HAL574  
Applications  
The HAL574 is a medium sensitive unipolar switching  
sensor (see Fig. 4–5).  
The HAL574 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.

IDDhigh  
In this two-wire sensor family, the HAL584 is a sensor  
with the same magnetic characteristics but with an  
inverted output characteristic.

the HAL574  
– typical temperature coefficient of magnetic switching  
points is 0 ppm/K  
– operates with static magnetic fields and dynamic  
magnetic fields up to 10 kHz  
Magnetic Characteristics at TJ = 40 °C to +140 °C, VDD = 4.3 V to 24 V,  
Typical Characteristics for VDD = 12 V

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
