HAL 503  
DATA SHEET  
4.3. HAL 503  
Applications  
The HAL 503 is a latching sensor (see Fig. 4–9).  
The HAL 503 is the optimal sensor for applications  
with alternating magnetic signals such as:  
The output turns low with the magnetic south pole on  
the branded side of the package and turns high with  
the magnetic north pole on the branded side. The out-  
put does not change if the magnetic field is removed.  
For changing the output state, the opposite magnetic  
field polarity must be applied.  
– multipole magnet applications,  
– rotating speed measurement,  
– commutation of brushless DC motors, and  
– window lifters.  
For correct functioning in the application, the sensor  
requires both magnetic polarities (north and south) on  
the branded side of the package.

Fig. 4–9: Definition of magnetic switching points for  
the HAL 503  
– typical temperature coefficient of magnetic switching  
points is 1000 ppm/K  
Magnetic Characteristics at TJ = 40 °C to +170 °C, VDD = 3.8 V to 24 V,  
Typical Characteristics for VDD = 12 V  
Magnetic flux density values of switching points.  
Positive flux density values refer to the magnetic south pole at 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
