Functional Description
The TLE4946-1L is an integrated circuit Hall-effect sensor designed specifically for highly
accurate automotive and industrial applications. Precise magnetic switching points and
high temperature stability are achieved by active compensation circuits and chopper
techniques on chip.

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.
