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.
