±0.005" [0.13 mm] die placement)
OPERATION
The output of these devices (pin 3) switches low when the mag-
netic 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 mechani-
cal vibration and electrical noise.
APPLICATIONS INFORMATION
Hall effect applications information is available in the “Hall-Effect
IC Applications Guide”, which can be found in the latest issue of
Allegro MicroSystems Data Book AMS-702.
