Operation
The output, I
CC
, of the A1140 and A1142 devices switch low
after the magnetic field at the Hall element exceeds the oper-
ate point threshold, B
OP
. When the magnetic field is reduced to
below the release point threshold, B
RP
, the device output goes
high. The differences 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 pres-
ence of external mechanical vibration and electrical noise. The
A1143 device switches with opposite polarity for similar B
OP
 
and B
RP
 values, in comparison to the A1140 and A1142 (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).
