The output, I
CC
, of the A1185 switches low 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 high. The differ-
ences 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. The A1186 device
switches with opposite polarity for similar B
OP
and B
RP
values,
in comparison to the A1185 (see figure 1).
Figure 1. Alternative switching behaviors are available in the A118x device family. 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).
