Potential Applications
The TLE5009A16(D) angle sensor is designed for angular position sensing in automotive and non-automotive
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 power-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.

GMR Angle Sensor
Description
The TLE5009A16(D) is an angle sensor with analog outputs. It detects the orientation of a magnetic field by
measuring sine and cosine components with Giant Magneto Resistive (GMR) elements. It provides analog sine
and cosine output voltages that describe the magnet angle in a range of 0° to 360°.
The differential MR bridge signals are independent of the magnetic field strength, and 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.
The sensor is available as single die version (TLE5009A16) and dual die version (TLE5009A16D) for safety
applications that require redundancy. The two versions are pin-compatible for easy scalability. In the dual die
TLE5009A16D, both sensor dice are supplied independently by separate supply and ground pins.

Functional Description
General
The Giant Magneto Resistive (GMR) 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, V
x
(cosine) or the
Y component, V
y
(sine)
The advantage of a full-bridge structure is that the amplitude of the MR signal is doubled and temperature
effects cancel out. 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°.

Attention:
Sensitive bridges of the GMR sensor (one die, not to scale)
Due to the rotational placement inaccuracy of the sensor IC in the package, the sensors 0° position
may deviate by up to 3° from the package edge direction indicated in
Figure 2.
In
Figure 2,
the arrows in the resistors represent the magnetic direction which is fixed in the Reference Layer.
On top of the Reference Layer, and separated by a non magnetic layer, there is a Free Layer. When applying an
external magnetic field the Free Layer moves in the same direction as the external magnetic field, while the
Reference Layer remains fix. The resistance of the GMR elements depends on the magnetic direction
difference between the Reference Layer and the Free Layer.
When the external magnetic field is parallel to the direction of the Reference Layer, the resistance is minimal
(Reference Layer and Free Layer are parallel). When the external magnetic field and the Reference Layer are
anti-parallel (Reference Layer and Free Layer are anti-parallel), resistance is maximal.
The output signal of each bridge is only unambiguous over 180° between two maxima. Therefore two bridges
are oriented orthogonally to each other to measure 360°.

GMR Angle Sensor
Functional Description
With the trigonometric function ARCTAN2, the true 360° angle value is calculated out of the raw X and Y signals
from the sensor bridges. The ARCTAN2 function is a microcontroller library function which resolves an angle
within 360° using the x and y coordinates on a unit circle.
