Product Description
1.1
Overview
The TLE5009 is an angle sensor with analog outputs. It detects the orientation of a magnetic field by measuring
sine and cosine angle components with Giant Magneto Resistance (GMR) elements. It provides analog sine and
cosine output voltages that describe the magnet angle in a range of 0 to 360°.
The differential GMR bridge signals are temperature compensated and independent of the magnetic field strength
to maintain constant output voltage over a wide temperature and field range. The analog output is designed for
differential applications.
The output voltages are designed to use the dynamic range of an A/D-converter using the same supply as the
sensor as voltage reference. Product type TLE5009-E2000 and TLE5009-E2010 are intended for use in circuits
with 5 Volts supply. Product types TLE5009-E1000 and TLE5009-E1010 are intended for use in 3.3V applications.
Product types TLE5009-E2010 and TLE5009-E1010 have improved angular accuracy achieved by production
trimming at two temperatures.

Target Applications
The TLE5009 GMR angle sensor is designed for angular position sensing in automotive applications. Its high
accuracy combined with short propagation delay makes it suitable for systems with high speeds and high accuracy
demands such as rotor position measurement for electric motor commutation. At the same time its fast start-up
time and low overall power consumption enables the device to be employed in low-power applications. Extremely
low power consumption can be achieved with power cycling, where the device excells with fastest power on time.

Functional Description
2.1
General
The GMR sensor is implemented using vertical integration. This means that the GMR sensitive areas are
integrated above the analog portion of the TLE5009 chip. These GMR elements change their resistance
depending on the direction of the magnetic field.
Four individual GMR elements are connected in a Wheatstone bridge arrangement. Each GMR element senses
one of two components of the applied magnetic field:
•
•
X component, Vx (cosine) or the
Y component, Vy (sine)
The advantage of a full-bridge structure is that the amplitude of the GMR signal is doubled and temperature effects
cancel out.

Sensitive bridges of the GMR sensor
Note: In Figure 1, the arrows in the resistors symbolize the direction of the reference layer. Size of the sensitive
areas is greatly exagerated for better visualisation.
The output signal of each bridge is unambiguous in a range of 180°. Therefore two bridges are oriented
orthogonally to each other to measure 360°.
With the trigonometric function ARCTAN, the true 360° angle value that is represented by the relation of X and Y
signals can be calculated according to Equation (1).

Calculation of the Junction Temperature
The total power dissipation PTOT of the chip increases its temperature above the ambient temperature.
The power multiplied by the total thermal resistance RthJA (Junction-to-Ambient) leads to a calculation of the final
junction temperature. RthJA is the sum of the addition of the values of the two components Junction-to-Case and
Case-to-Ambient.
RthJA = RthJC + RthCA

Output Parameters
All parameters apply over the full operating range, unless otherwise specified. The parameters in Table 6 refer to
single-ended output and Table 7 to differential output. For variable names please refer to Figure 7 “Single-ended
output signals” on Page 17 and Figure 8 “Differential output of ideal cosine” on Page 18.
The following equations describe various types of errors that combine to the overall angle error.
The maximum and zero-crossing of the SIN and COS signals do not occur at the precise angle of 90°. The
difference between the X and Y phases is called the orthogonality error. In Equation (4) the angle at zero
crossing of the X cosine output is subtracted from the angle at the maximum of the Y SIN output, which describes
the orthogonality of X and Y.
(4)
ϕ = α [Ymax ] − α [ X 0 ]
The amplitudes of SIN and COS signals are not equal to each other. The amplitude mismatch is defined as
syncronism, shown in Equation (5). This value could also be described as amplitude ratio mismatch.

Calibration of TLE5009
This chapter explains how to determine the Giant MagnetoResistance (GMR) parameters such as amplitude,
offset, and the phase of X- and Y-channels. Extraction of these parameters is essential to achieve the angle
accuracy given in Table 8 “Angle performance in differential applications” on Page 25.
The end-of-line calibration is accomplished using the following sequence (Figure 9):
1.) left turn measurement

2. Calculate amplitude, offset, phase correction values of left turn
3. Turn further 90° left and 90° back right without measurement
4. Turn magnetic field 360° right and measure X and Y values
5. Calculate amplitude, offset, phase correction values of right turn
6. Calculate mean values of amplitude, offset, phase correction
The calibration has to be done at room temperature with a magnet in the specified magnetic field range.
3.4.4.1
Extraction of Parameters
There are two possible methods for extracting these parameters. The methods will be discussed in more detail in
the next two sections.

distance of 90°. The difference between X and Y phases is called the orthogonality error (Equation (13)):

Figure 11 Orthogonality error
There is another more accurate way to determine the orthogonality error. The orthogonality can be calculated out
of the magnitude of two 90° angle shifted components. Possible angle combinations are 45° and 135°, 135° and
225°, 225° and 315° or 315° and 45°.
The angle value is given by the angle sensor. No reference is necessary. Therefore the final parameters of
amplitude and offset (Chapter 3.4.4.2) should be used.
At an angle output of 45° the corresponding Y(sin) and X(cos) values can be read out. This has been done also
at 135° (Figure 12).
Next step is to calculate the length of the magnitudes (Equation (14)):

With these magnitudes the orthogonality can be calculated (Equation (15)):

Exact Method
This method uses the Discrete Fourier Transform (DFT) to extract the parameters out of the measurements.
Therefore an accurate reference system is necessary. This method is done using 2m measurement points at 360°
(e.g. m = 8; n = 2m = 28 = 64).
DFT Offset Calculation:
The offset is calculated by the summation of the X- or Y- measurements divided by the number of measurement
points (Equation (16)):

DFT Amplitude and Phase Calculation:
To determine the amplitude, the real and imaginary parts must be calculated. This has been done with
Equation (17) for the X values and Equation (18) for the Y values. ß describes the reference angle (e.g. n = 64;
measurement every 360° / 64 = 5.625° step).

No matter what calibration method is used, you still have to calculate the symmetrical values of the parameters.
This is done using the mean value of the clock-wise (cw) rotation parameters and counterclock-wise (ccw) rotation
parameters. This calculation has to be done with X and Y parameters. These parameters have to be used for the

Angle Performance
The overall angle error represents the relative angular error. This error describes the deviation from the reference
line after zero angle definition. The typical value correspond to a supply voltage VDD = 3.0V - 5.5 V and 25 °C,
unless individually specified. All other values correspond to -40°C < TJ < 150°C.
Calibration of offset, orthogonality, syncronism and phase error at 25°C are required to achieve the overall angle
error specified. For the detailed calibration procedure refer to Chapter 3.4.4.
Infineon offers temperature compensated versions of the device TLE5009-E2010, TLE5009-E1010. These

Safety Features
3.5.1
Built in error diagnosis
The device sensor provides two functions at the VGMR pin. During normal operation the voltage measured at this
pin is temperature dependent. The typical voltage at room temperature and the temperature coefficient are given
in Table 4 “Electrical parameters” on Page 15.
The second purpose of pin VGMR is the diagnosis functionality. In case the device detects an internal error, the pin
is driven to a low level as described in Table 4 “Electrical parameters” on Page 15.
The errors that can be detected by monitoring the status of the VGMR pin are:
•
•
•
Start-up failure
Overvoltage at VDD (threshold level min. 6V, max. 7V)
Undervoltage at internal nodes
3.5.2
External Diagnosis
Adressing the demands for functional safety, run time checks can be done to increase the diagnostic coverage.
Depending on the application specifics such as the available time and processing capabilities, the sensor
behaviour is monitored and compared with the specified behaviour of the device.
3.5.2.1
Vector length check differential voltage mode
A comprehensive safety check is to monitor the vector length of Vx and Vy signals. Output signals representing
sine and cosine have a fixed 90° phase relationship to each other. To determine if the output signals are valid, the
length of the output vector length must be nearly constant independent of the magnet position.
The vector length corresponds to the amplitude of the output signals and utilizes the fact that there is a 90° phase
shift between sine and cosine output. It is calculated according to Equation (26).
As illustrated in Figure 14 “Valid vector length”, the vector describes a circle along one revolution of the magnet.
The length of the vector is almost constant, slightly influenced by GMR synchronicity, orthogonality, offset and
temperature.

The resulting vector length must always be within the range given in Table 9, depending on the supply voltage
type of the TLE5009 used. If the vector length is outside this range, then this might indicate malfunction of the
TLE5009 or of the reading A/D converter.
