Developed for automotive applications. Product qualification according to AEC-Q100. Potential Applications
The TLE5x0916(D) angle sensors are designed for angular position sensing in safety critical automotive and
non-automotive applications. Their high accuracy combined with short propagation delay make especially
the GMR sensor variants 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). The AMR sensor variants with their
typically accuracy of 0.1° fit for systems with high speeds and high accuracy demands such as pedals, levers
or brush-less DC (BLDC) motors with an even number of pole pairs. At the same time their 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. Potential applications are:
• BLDC motors • Pedals and rotary switches • Steering angle sensing • Valve or flap position sensing Data Sheet www.infineon.com/sensors 1 V 2.0

Analog AMR/GMR Angle Sensor Figure 1 A usual application for TLE5x09A16(D) is the electrically commutated motor Description
The TLE5x0916(D) are angle sensor with analog outputs. They detect the orientation of a magnetic field by
measuring sine and cosine angle components with 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. There are single die and dual die combinations with a Giant Magneto
Resistance (GMR) …
