Operation
The output, I
CC
, of the A1145 device switches low after the mag-
netic field at the Hall sensor 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 A1146 device
switches with opposite polarity for similar B
OP
and B
RP
values,
in comparison to the A1145 (see figure 1).
Figure 1. Alternative switching behaviors are available in the A114x 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).
