Functional Description
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.
1.1
Sensor Assembly
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) of 5 mm the
direction signal achieves a phase shift of 90° compared to the speed signal.
Sensor and back bias magnet can be applied in the following ways:

Block Diagram
The speed signal calculated out of B2-B1, is amplified, low pass filtered and digitized. An algorithm in the digital
core for peak detection and offset calculation will be executed. The offset is fed back into the speed signal path
with a digital to analog converter for offset correction. The adaptive hysteresis comparator compares the
speed signal to the hysteresis value. During uncalibrated mode, the output of the speed pulse is triggered in
the digital core by exceeding a certain threshold.
The direction signal is calculated out of the three Hall signals. The direction signal is amplified, filtered, and
digitized. In the digital core the direction and the vibration detection information is determined and the data
protocol is issued. The direction information is converted to a current modulated signal.

Operating Modes and States

Operating Modes and States
2.1
Uncalibrated and Calibrated Mode
After power on the differential magnetic speed signal is tracked by an analog to digital converter (Tracking
ADC) and monitored within the digital core. If the signal slope is identified as a rising edge, the first output
pulse is triggered. A second trigger pulse is issued as soon as the next rising edge is detected (see Figure 4 ). In
uncalibrated mode, the output protocols are triggered by the DNC (detection noise constant) in the speed
path. After start up the first DNC value is set to 2xΔBspeed- limit and after that the DNC is adapted to the magnetic
input signal amplitude (ΔBspeed) with a minimum of 2xΔBspeed-limit
.
The offset update starts if two valid extrema values are found and the direction of the update has the same
orientation as the magnetic signal. For example, a positive offset update is being issued on a rising magnetic
edge only. The offset update is done independent from the output switching. After a successful offset
correction, the sensor is in calibrated mode. Switching occurs at the adaptive hysteresis threshold level.
In calibrated mode, the DNC is adapted to magnetic input signal amplitude (as ΔBspeed /2) with a minimum of
2xΔBspeed-limit. The output pulses are then triggered with adaptative hysteresis.
In uncalibrated mode (after start-up or reset) for signals with amplitude smaller than 2*ΔBlimit (either for
direction or speed signal), the sensor always provides the first two pulses and could suppress the third one.
The pulse corresponding to the fourth magnetic period is calibrated, thus including the direction information.

2.2
Adaptive Hysteresis
The adaptive hysteresis is linked to the input signal. Therefore, the system is able to suppress switching if
vibration or noise signals are smaller than the adaptive hysteresis levels. The typical value for the hysteresis
level is 1/8 of the magnetic input signal amplitude, the minimum hysteresis level is ΔBspeed-limit (amplitude).
The visible hysteresis keeps the excellent performance in large pitch transmission application wheels .

Operating Modes and States
2.3
Direction Detection
The difference between the Hall element signal B3 and the mean value of the outer Hall elements B2 and B1 will
be calculated in the direction input amplifier. This signal is digitized by an analog to digital converter
(direction ADC) and fed into the digital core.
Depending upon the rotation direction of the target wheel, the signal of the center probe anticipates or lags
behind for 90°. This phase relationship is evaluated and converted into rotation direction information by
sampling the signal of the center probe in the proximity of the zero crossing of the “speed” bridge signal.
The first pulse after power on is a speed pulse, as there is no valid direction information available.
2.4
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 air gap vibrations. If an input signal is
identified as a vibration the output pulse will be suppressed.
TLE4955C offers two different kinds of vibration suppression:
•
•
Vibration suppression via hysteresis. This is available after power on
Vibration suppression via direction detection. This is available after start up calibration is performed.
2.5
Undervoltage Behavior
At the first switching events after power on the undervoltage detection is activated.
If the supply voltage drops below the values specified in operating range, an active output (defined state) will
be generated. The output level is switched to high current (IHigh) and it remains at this level until the supply
voltage reaches again the functional level.

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.

TLE4955C E4
The Infineon XENSIV differential Hall sensor IC from Infineon 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. The magnetic sensor provides high magnetic sensitivity. TLE4955C-E4 includes a sophisticated algorithm which actively suppresses vibration while keeping excellent air-gap performance.
