General
1.1
Target Application
TLE4954C/51C is an integrated differential Hall effect sensor for transmission applications with two wire PWM
current interface. Its basic function is to provide information about rotational speed and direction of rotation to the
transmission control unit. TLE4954C/51C includes a sophisticated algorithm which actively suppresses vibration
while keeping excellent airgap performance. Infineon also offers customers the possibility to purchase sensors
with already attached back bias magnets (CB versions).

Functional Description
2.1
General
The differential Hall sensor IC detects the motion of tooth and magnet encoder applications. To detect the motion
of ferromagnetic objects, the magnetic field must be provided by a back biasing permanent magnet. Either south
or north pole of the magnet can be attached to the rear unmarked side of the IC package. The magnetic
measurement is based on three equally spaced Hall elements, integrated on the IC. Both magnetic and
mechanical offsets are cancelled by a self calibration algorithm. The sensor includes a current output PWM
protocol.

Figure 2-1 Sensor assembly and definition of rotating directions
The output signals for a south biased sensor with a magnetic encoder and ferromagnetic tooth wheel will be issued
in the following way.
The tooth wheel is rotating in clockwise above the sensor. The output pulse will be issued by reaching the
hysteresis levels after the pre low time. For a tooth wheel with ideal pitch (tooth to tooth) 5mm the direction signal
achieves a phase shift of 90° compared to the speed signal.

Vibration Suppression
TLE4954C offers two different kinds of vibration suppression:
The magnetic signal amplitude and the direction information are used for detection of parasitic magnetic signals.
Unwanted magnetic signal can be caused by angular or airgap vibrations. If an input signal is identified as a
vibration the output pulse will be suppressed.

•
Vibration suppression via hysteresis. This is available after power on
Vibration suppression via direction detection. This is available after start up calibration is performed.

Timing Characteristics
Between each magnetic transition and the rising edge of the corresponding output pulse, the output current is low
for tpre-low in order to allow reliable internal conveyance. After pre low time the output current level is set to high.
After power on the speed pulse is being issued. As soon as the sensor has enough information to recognize the
direction of the target wheel, the output pulse will include the direction information.
Rotation direction is evaluated only for low rotation speed. The speed signal will be delivered again if the magnetic
frequency is above fDR,max
