(B) Hysteresis curve for A1193
Figure 1. Alternative switching behaviors are available in the A119x 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).
The A1190 and A1192 output, ICC, switches low after the mag-
netic field at the Hall sensor IC exceeds the operate point thresh-
old, BOP. When the magnetic field is reduced to below the release
point threshold, BRP, the device output goes high. This is shown
in figure 1, panel A.
In the case of the reverse output polarity, as in the A1193, the
device output switches high after the magnetic field at the Hall
sensor IC exceeds the operate point threshold, BOP. When the
magnetic field is reduced to below the release point threshold,
BRP, the device output goes low (panel B).
The difference between the magnetic operate and release points
is called the hysteresis of the device, BHYS. This built-in hyster-
esis allows clean switching of the output even in the presence of
external mechanical vibration and electrical noise.
