Operation
The output, I
CC
, of the A1184 device switches high after the
magnetic field at the Hall element exceeds the operate point
threshold, B
OP
. When the magnetic field is reduced to below the
release point threshold, B
RP
, the device output goes low. The dif-
ferences between the magnetic operate and release point is called
the hysteresis of the device, B
HYS
. This built-in hysteresis allows
clean switching of the output even in the presence of external
mechanical vibration and electrical noise. (See figure 1).
Figure 1. On the horizontal axis, the B+ direction indicates
increasing south polarity magnetic field strength, and the
B direction indicates decreasing south polarity field strength
(including the case of increasing north polarity).
