A1190, A1192,
and A1193
The A1190 and A1192 output, I
netic field at the Hall sensor IC exceeds the operate point thresh-
old, B
point threshold, B
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
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 difference between the magnetic operate and release points
is called the hysteresis of the device, B
esis allows clean switching of the output even in the presence of
external mechanical vibration and electrical noise.
