TLE4959C FX Flexible Transmission Speed Sensor  
Description  
The TLE4959C FX comes in a RoHs compliant three-pin package, qualified for automotive usage. It has two  
integrated capacitors on the lead frame (220 nF/1.8 nF). These capacitors increase the EMC robustness of the  
device. In 12 V applications it is further recommended to use a serial resistor RSupply of 100 Ω (tbd) for  
protection on the supply line. A pull-up resistor RLoad is mandatory on the output pin and determines the  
maximum current flowing through the output transistor. A value of 1.2 kΩ is recommended for the 5V  
application. (see Figure 1)

Functional Description

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 (See  
Figure 2). 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.  
1.1  
Definition of the Magnetic Field Direction  
The magnetic field of a permanent magnet exits from the north pole and enters the south pole. If a north pole  
is attached to the backside of the High End Transmission Sensor, the field at the sensor position is positive, as  
shown in Figure 2.

Functional Description  
1.3  
Basic Operation  
The speed signal calculated out of the differential hall elements, is amplified, 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. During uncalibrated mode,  
the output of the speed pulse is triggered in the digital core by exceeding a certain threshold of the tracking  
ADC. In calibrated mode the output is triggered by the visible hysteresis.  
The direction signal is calculated out of center 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  
output protocol is issued.  
1.4  
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 or falling edge, the  
first output pulse is triggered. A second trigger pulse is issued with direction information.  
In uncalibrated mode, the output protocols are triggered by the DNC (detection noise constant) in the speed  
path. After start up the sensor switches with the DNC min value and after that the DNC is adapted to the  
magnetic input signal amplitude.  
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. 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 with a minimum of  
ΔBlimit . The output pulses are then triggered with adaptive hysteresis.  
1.5  
Hysteresis Concept  
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 minimum hysteresis level is  
ΔBlimit  
.
The visible hysteresis keeps the excellent performance in large pitch transmission application wheels.

Functional Description  
1.6  
Rotational Direction  
The direction 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 (power on pulse) has a different length to signalize that there is no direction  
information available .  
Forward pulse (tfwd) is issue if the wheel rotates from pin 1 to pin 3  
Backward pulse (tbwd) is issue if the wheel rotates from pin 3 to pin 1  
Forward/backward pulse length could be inverted via EEPROM settings.

Direction definition  
In case of high speed has been enable, the direction detection is switched off as soon as the frequency reach  
4.3 kHz. To enter or leave the high frequency, two consecutive periods have to be larger or smaller than the  
frequency limit. this may delay the high frequency pulse at power on.  
1.7  
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.

EEPROM Functional Description

EEPROM Functional Description  
4.1  
Serial Interface  
The serial interface is used to set parameter and to program the sensor IC, it allows writing and reading of  
internal registers. Data transmission to the IC is done by supply voltage modulation, by providing the clock  
timing and data information via only one line. Data from the IC are delivered via the output line, triggered by  
as well clocking the supply line. In normal application operation the interface is not active, for entering that  
mode a certain command right after power-on is required.  
A detailed document (TLE4959C FX EEPROM Programming Guide) is available on request. It contains the  
description of electrical timing and voltage requirements, as well as the information about data protocol,  
available registers and addresses.  
4.1.1  
Data Transmission  
Commands to the sensor are sent by modulating the supply voltage between two levels VDD,high and VDD,low  
.
They are sent in series of 17 pulses corresponding to 16 bit words, with MSB transmitted first and LSB last,  
respectively the stop bit. Each of the 16 pulses is coded by the duty cycle as logical “0” or “1”. Logical "1" is  
represented by a duty cycle of 2/3 of the period on VDD,high, logical “0” is represented by a duty cycle of 1/3 at  
VDD,high. This forms the bit information and acts also as serial interface clock. Data transmission from the device  
is represented by the state of the output, high for logical “1” and low for logical “0”. Recommended period  
length is around 200 (tbd) µs per bit.  
End of word is indicated by a long "low" supply (> 750 ms, first 30 ms should be > VDD,high, remaining time  
< VDD,low). Please note, that for transmission of 16 data bits in total 17 pulses on VDD are necessary. If more than  
16 input bits are transmitted the output bits are irrelevant (transmission buffer empty), whereas the input bits  
remain valid and start overwriting the previously transmitted bits. In any case the last 17 transmitted bits are  
interpreted as transmitted data word (16 bit) + 1 stop bit.

TLE4959C FX Flexible Transmission Speed Sensor  
EEPROM Functional Description  
4.2  
EEPROM Description  
Several options of TLE4959C FX can be programmed via an EEPROM to optimize the sensor algorithm to the  
individual target wheel and application requirements. The EEPROM memory is organized in 2 customer lines.  
Each line is composed of 16 data bits and additional 6 bits for error detection and correction, based on ECC  
(Error Correction Code). For more detailed information about EEPROM access and programming an additional  
document is available on request.
