HAL5xx  
Hall Effect Sensor Family  
1.2. Family Overview  
in CMOS technology  
The types differ according to the magnetic flux density  
values for the magnetic switching points, the tempera-  
ture behavior of the magnetic switching points, and the  
mode of switching.  
Release Notes: Revision bars indicate significant  
changes to the previous edition.

Page  
The HAL5xx family consists of different Hall switches  
produced in CMOS technology. All sensors include a  
temperature-compensated Hall plate with active offset  
compensation, a comparator, and an open-drain output  
transistor. The comparator compares the actual mag-  
netic flux through the Hall plate (Hall voltage) with the  
fixed reference values (switching points). Accordingly,  
the output transistor is switched on or off.

The sensors of this family differ in the switching behavior  
and the switching points.  
high  
The active offset compensation leads to constant mag-  
netic characteristics over supply voltage and tempera-  
ture range. In addition, the magnetic parameters are ro-  
bust against mechanical stress effects.  
medium  
low  
The sensors are designed for industrial and automotive  
applications and operate with supply voltages from  
3.8 V to 24 V in the ambient temperature range from  
–40 °C up to 150 °C.

– magnetic characteristics are robust against mechani-  
cal stress effects  
Latching Sensors:  
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 output  
does not change if the magnetic field is removed. For  
changing the output state, the opposite magnetic field  
polarity must be applied.  
– short-circuit protected open-drain output by thermal  
shut down  
– operates with static magnetic fields and dynamic mag-  
netic fields up to 10 kHz  
– constant switching points over a wide supply voltage  
range  
Bipolar Switching Sensors:  
– the decrease of magnetic flux density caused by rising  
temperature in the sensor system is compensated by  
a built-in negative temperature coefficient of the mag-  
netic characteristics  
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 output  
state is not defined for all sensors if the magnetic field is  
removed again. Some sensors will change the output  
state and some sensors will not.  
– ideal sensor for applications in extreme automotive  
and industrial environments  
– EMC corresponding to DIN 40839
