Functional Description
The TLE4966-3G is an integrated circuit dual Hall-effect sensor designed specifically for highly accurate
applications which use a rotating pole wheel. Precise magnetic switching points and high temperature stability are
achieved by active compensation circuits and chopper techniques on chip. The sensor provides a speed output
at Q2 with the status (high or low) corresponding to the magnetic field value. For positive magnetic fields (south
pole) exceeding the threshold B
OP
the output is low, whereas for negative magnetic fields (north pole) lower than
B
RP
the output switches to high. The output Q1 can be either high or low depending on the direction of rotation of
the pole wheel. This direction information is calculated internally.
