Product Description
1.1
Overview
The TLE5012 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
(iGMR) elements.
High precision angle values are achieved over temperature and lifetime
using internal autocalibration algorithm.
Data communications are accomplished with a bi-directional SSC
Interface that is SPI compatible.
The absolute angle value and other values are transmitted via SSC or via a Pulse-Width-Modulation (PWM)
Protocol. Also the sine and cosine raw values can be read out. These raw signals are digitally processed internally
to calculate the angle orientation of the magnetic field (magnet).
The TLE5012 is a precalibrated sensor. The calibration parameters are stored in laser fuses. At start-up the values
of the fuses are written into Flip-Flops, where these values can be changed by the application specific parameters.
The TLE5012-E0318 and TLE5012-E0742 are especially configured in a Hall-Switch emulation mode for motors
with three or seven pole pairs.
Online diagnostic functions are provided to ensure reliable operation.
