OPERATION
The output of these devices (pin 3) switches low when the magnetic field
at the Hall sensor exceeds the operate point threshold (B
OP). At this point, the
output voltage is V
OUT(SAT). When the magnetic field is reduced to below the
release point threshold (B
RP), the device output goes high. The difference in
the magnetic operate and release points is called the hysteresis (B
hys) of the
device. This built-in hysteresis allows clean switching of the output even in
the presence of external mechanical vibration and electrical noise.
Extensive applications information for Hall-effect sensors is available in:
