The differential Hall Effect sensor TLE4921-5U provides a high sensitivity and a *ior
stability over temperature and symmetrical thresholds in order to achieve a stable duty
cycle. TLE4921-5U is particularly suitable  for rotational speed  detection and timing
applications of ferromagnetic toothed wheels such as  anti-lock braking systems,
tran*issions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a
di*al signal output with frequency proportional to the speed of rotation. Unlike other
rotational sensors differential Hall ICs are not  influenced by radial vibration within the
effective airgap of the sensor and require no external signal processing.

2.2 Functional Description
The Differential Hall Sensor IC detects the motion and position of ferromagnetic and
permanent magnet structures by measuring the differential flux density of the magnetic
field. To detect ferromagnetic objects the magnetic field must be provided by a back
biasing permanent magnet (south or north pole of the magnet attached to the rear
unmarked side of the IC package).
Using an external capacitor the generated Hall voltage signal is slowly adjusted via an
active high p* filter with a low cut-off frequency. This causes the output to switch into
a biased mode after a time constant is elapsed. The time constant is determined by the
external capacitor. Filtering avoids ageing and temperature influence from Schmitt-
trigger input and eliminates device and magnetic offset.
The TLE4921-5U can be exploited to detect toothed wheel rotation in a rough
environment. Jolts against the toothed wheel and ripple have no influence on the output
signal.
Furthermore, the TLE4921-5U can be operated in a two-wire as well as in a three-wire-
configuration.
The output is logic compatible by high/low levels regarding on and off.
