Product Description
1.1
Overview
The TLE5012 is a 360° angle sensor that detects the orientation of a
magnetic field by measuring sine and cosine angle components with
monolithic integrated Giant Magneto Resistance (iGMR) elements.
Highly precise angle values are maintained at various temperatures
throughout the device’s lifetime using an internal autocalibration
algorithm.
Data communications are accomplished with a bi-directional
Synchronous Serial (SSC)-Interface that is Serial Peripheral Interface (SPI)-compatible.
The absolute angle value and other values are transmitted via SSC or via a Pulse-Width Modulation (PWM)
protocol. The sine and cosine raw values can also 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.
