The TLE4966-3K 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.
