TLE5011
Overview
1.2
Target Applications
The TLE5011 GMR-Based Angular Sensor is designed for angular position sensing in
automotive applications, such as:
• Steering Angle
• Brushless DC Motor Commutation (e.g. EPS)
• Rotary Switch
• General Angular Sensing
1.3
Product Description
The TLE5011 is a 360° angle sensor that detects the orientation of a magnetic field. This
is achieved by measuring sine and cosine angle components with monolithic integrated
Giant Magneto Resistance (GMR) elements.
Data communications are accomplished with a bi-directional SSC Interface that is SPI
compatible.
The sine and cosine values can be read out. These signals can be digitally processed
to calculate the angle orientation of the magnetic field (magnet). This calculation can be
done by using a cordic algorithm.
It is possible to connect more than one TLE5011
to one SSC Interface of a
microcontroller for redundancy or any other reasons.If multiple TLE5011 devices are
used, the synchronization of the connected TLE5011 is performed by a broadcast
command. Each connected TLE5011 can be addressed by a dedicated Chip Select CS
pin.
Online diagnostic functions are provided to ensure a reliable operation.
These are
• Angle test (generated via test voltages feeding the ADC).
• Crossed signal paths (switchable for comparison)
• Inverted signs of bit streams
• Over and undervoltage detections
