Functional Description
When a positive magnetic field is applied in the indicated direction (figure 2) and the turn-ON
B
magnetic induction
is exceeded, the output of the Hall-effect IC will conduct (Operate Point).
OP
When the current is reduced (TLE 4904) or a reverse magnetic field is generated (TLE 4934,
TLE 4944), the output of the IC turns OFF (Release Point) (figures 3 and 4).
B
and
B
are the critical parameters in most unipolar and bipolar Hall-switch applications. For
RP
OP
this reason the switching points are adjusted.
