TLE 4905/35/35-2/45 L (Unipolar/Bipolar Magnetic Field Switches) have been designed
specifically for automotive and industrial applications. Reverse polarity protection is
included on-chip as is output protection against negative voltage transients.
Typical applications are position/proximity indicators, brushless DC motor commutation,
rotational indexing etc.

Functional Description Bipolar Type TLE 4935/35-2/45 (figure 5 and 6)
When a positive magnetic field is applied in the indicated direction (figure 5) and the
turn-on magnetic induction BOP is exceeded, the output of the Hall-effect IC will conduct
(Operate Point). When a reverse magnetic field is generated, the output of the IC turns
off (Release Point; figure 6).
