Functional Description
The TLE4966H is an integrated circuit double Hall-effect sensor designed specifically for
highly accurate applications. Precise magnetic switching points and high temperature
stability are achieved by active compensation circuits and chopper techniques on chip.
The TLE4966H provides a speed signal at Q2 for every magnetic pole pair and a direction
information at Q1. The direction output switches 1µs (min.) before the speed output.

1) To operate the sensor at the max. switching frequency, the value of the magnetic signal
amplitude must be 1.4 times higher than for static fields. This is due to the -3dB corner frequency
of the low pass filter in the signal path.
2) Systematic delay between magnetic threshold reached and output switching.
3) Jitter is the unpredictable deviation of the output switching delay.

e.g.: VS=12.0 V, IS_typ=5.5 mA, VQSAT_typ=0.3 V, 2*IQ=10mA => Power Dissipation Pdis= 72.0 mW.
In TA = Tj – (RthJA * Pdis) = 175 °C – (100 K/W * 0.072 W) => TA = 167.8 °C
