Potential Applications
The TLE5309D angle sensor is designed for angular position sensing in safety critical automotive and nonautomotive applications. Its high accuracy and 360° measurement range combined with short propagation
delay makes it suitable for systems with high speeds and high accuracy demands such as brush-less DC (BLDC)
motors for actuators and electric power steering systems (EPS). At the same time its fast start-up time and low
overall power consumption enables the device to be employed for low-power turn counting. Extremely low
power consumption can be achieved with power cycling, where the advantage of fast power on time reduces
the average power consumption.

TLE5309D
Dual GMR/AMR Angle Sensor
Description
The TLE5309D is a diverse redundant angle sensor with analog outputs. It combines a Giant Magneto
Resistance (GMR) sensor for full 360° angle range with an Anisotropic Magneto Resistance (AMR) sensor for
high precision in a flipped configuration in one package. Sine and cosine angle components of a rotating
magnetic field are measured by Magneto Resistive (MR) elements. The sensors provide analog sine and cosine
output voltages that describe the magnetic angle in a range of 0 to 180° (AMR sensor), and 0 to 360° (GMR
sensor), respectively.
The differential MR bridge signals are independent of the magnetic field strength, and the analog output is
designed for differential or single-ended 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. Both sensor ICs are supplied independently by separate supply and ground pins.

Functional description
1.1
General
The TLE5309D comprises one GMR-based angle sensor IC mounted on the top and one AMR-based angle
sensor IC mounted on the bottom of a package lead frame in a flipped configuration, so the positions of the
sensitive elements in the package-plane coincide. This mounting technique ensures a minimum deviation of
the magnetic field orientation sensed by the two chips.
The Magneto Resistive (MR) sensors are implemented using vertical integration. This means that the MR
sensitive areas are integrated above the analog portion of the ICs. These MR elements change their resistance
depending on the direction of the magnetic field.
On each sensor, four individual MR elements are connected in a Wheatstone bridge arrangement. Each MR
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 MR signal is doubled and temperature
effects cancel out.
GMR Sensor
The output signal of a GMR bridge is unambiguous in a range of 180°. Therefore two bridges are oriented
orthogonally to each other to measure 360°.

Functional description

Dual die angle output
The bottom sensor element of the TLE5309D is an AMR sensor, the signal of which is only unambiguous over
180°. Therefore, in the angle range of 180° to 360° of the GMR sensor, the AMR sensor output signal will be in a
range of 0° to 180° again. This behavior is illustrated in Figure 8, which shows the angle calculated according
to Equation (1) and Equation (2) from the output of the GMR and AMR sensors, respectively, for a given
external magnetic field orientation.
If in an application a different output of the two sensors is desired, the connections to the SIN_N and SIN_P or
COS_N and COS_P pins on the printed circuit board can be interchanged. The consequence of this change of
connections is that either the differential sine or the cosine signal are inverted, which corresponds to a change
of rotation direction (see dashed line in Figure 8).

The positioning accuracy of each sensor IC in the package is ±3°. Thus, the relative rotation of the
two sensor ICs can be up to 6°, resulting in a constant offset of the angle output of up to 6°, which has
to be measured in an end-of-line calibration and taken into account during operation of the
TLE5309D.

The TLE5309D sensor can be used in single-ended or differential output mode. Figure 9 shows a typical
application circuit for the TLE5309D in single-ended output mode using the positive output channels. For
single-ended operation the positive or negative output channels can be used. Unused single-ended output
pins should preferably be floating or connected to GND with a high-ohmic resistance (> 100 kΩ). The TLE5309D
has separate supply pins for the GMR sensor and the AMR sensor. The microcontroller comprises up to 10 A/D
inputs used to receive the sensor output signals in differential output mode, illustrated in Figure 10. For
reasons of EMC and output filtering, the following RC low pass arrangement is recommended. The RC low pass
has to be adapted according to the applied rotation speed. 1)

Application circuit for the TLE5309D in differential output mode
Application circuit for low-power consumption (e.g. turn counter)
Applications that use electric motors and actuators may require a turn counter function. A turn counter
function allows to keep track of the electric motor or actuator position with low-power consumption. During
operation the sensor is powered on, therefore the angle information is constantly available and, if necessary,
stored. But when the system is not in operation the sensor is powered off to save power consumption,
therefore rotational movements are not detected. To avoid missing the position the sensor can be awaked
periodically to obtain the angle information. The minimum length of the awake time must cover the TLE5309D
power-up time (described in Table 5) and the required time to transmit the data, which is also dependent on
the application circuit.
An optimal TLE5309D application circuit for systems with turn counter function is shown in Figure 11 for
single-ended output respectively in Figure 12 for differential output. With a lower resistor and capacitor
design the low-pass filter has a time constant of only a few microseconds. Therefore, the time needed to
supply the TLE5309D with power in order to read the output signal is considerably reduced.

to single pin output and Table 7 to differential output. For variable names please refer to Figure 15 “GMR
sensor single-ended output signals” on Page 18 and Figure 17 “GMR differential output of ideal cosine” on
Page 19.
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 (3) the angle at zero
crossing of the X COS output is subtracted from the angle at the maximum of the Y SIN output, which describes
the orthogonality of X and Y.
(3)
The amplitudes of SIN and COS signals are not equal to each other. The amplitude mismatch is defined as
synchronism, shown in Equation (4). This value could also be described as amplitude ratio mismatch.

Error diagnosis
Each sensor provides two functions at its VDIAG 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 5 “Electrical parameters” on Page 16.
The second purpose of pin VDIAG is the diagnosis functionality. In case the device detects an internal error, the
pin is driven to a low level. The errors that can be detected by monitoring the status of the VDIAG pin are:
•
Overvoltage at VDD (supply)
•
Undervoltage at VDD (supply)
•
Undervoltage at internal nodes (analog voltage regulator and/or GMR voltage regulator)
•
Bandgap failure (temperature)
•
Oscillator failure (only tested at startup)
•
Parity check of configuration fuses (only tested at startup)
Not all the failure conditions that are detected by the VDIAG pin are also detected by the alternative
configuration with pull-down resistors described in Figure 14. For further details please refer to the Safety
Manual.
2.5
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 corresponds to an ambient temperature of 25°C. All
other values correspond to the operating ambient temperature range -40°C < TA < 125°C and through the
TLE5309D lifetime.
Fully compensated performance
Using the algorithm described in the application note “TLE5009 Calibration”, it is possible to implement an
ongoing automatic calibration on the microcontroller to greatly improve the performance of the TLE5309D, as
temperature and lifetime drifts are better compensated. This is only possible in applications where a rotor is
turning continuously.

With this auto calibration algorithm, it is possible to reach an angular accuracy as good as the residual error

synchronicity mismatch for both the AMR and the GMR sensors and perfect compensation of orthogonality
error for the GMR sensor. A typical behavior of a fully compensated angle error with this ongoing calibration is
shown in Figure 19 for the GMR sensor and Figure 20 for the AMR sensor for different ambient temperatures.
The accuracy of the fully compensated angle is listed in Table 8, which is divided into single-ended and
differential output of the sensor.
Angle performance with one-time calibration
To achieve the overall angle error specified, both sensor ICs in the TLE5309D have to be calibrated for offset
and amplitude synchronism at 25°C. Additionally, the GMR sensor has to be calibrated for orthogonality. The
compensation parameters have to be stored and applied on the microcontroller. For the detailed calibration
procedure refer to the application note “TLE5009 Calibration”. Table 9 characterizes the accuracy of the
angle, which is calculated from the single-ended output respectively the differential output of the sensor and
the compensation parameters acquired in the end-of-line calibration.

Typical behaviour of angle error compensation
The angle accuracy performance for ideal compensation and one-time compensation is listed in Table 8
respectively in Table 9. Figure 19 shows for the GMR sensor and Figure 20 for the AMR sensor the typical
behavior of the residual angle error with ongoing respectively one-time calibration at different ambient
temperatures. The comparison of this compensation algorithms demonstrates the superior performance of
the full compensation method over lifetime and temperature with an average residual error below 0.6° for the
GMR sensor and 0.1° for the AMR sensor operating in the specified magnetic field. With one-time
compensation an additional residual angle error occurs due to the temperature dependency of the sensor.
