Operation
The output, I
after the magnetic fi eld at the Hall element exceeds the oper-
ate point threshold, B
below the release point threshold, B
high. The differences between the magnetic operate and release
point is called the hysteresis of the device, B
Figure 1. Alternative switching behaviors are available in the A118x device family. On the horizontal axis, the B+ direction indicates
increasing south polarity magnetic fi eld strength, and the B– direction indicates decreasing south polarity fi eld strength (including the
case of increasing north polarity).
