Additional Details:

The TLE5011G requires an external rotating magnetic field generated by a permanent magnet placed above or below the sensor. The sensor detects the direction of the magnetic field and converts it into an angular position. The output signal is typically transmitted via an SPI (Serial Peripheral Interface) or SENT (Single Edge Nibble Transmission) interface. Careful alignment of the magnet and sensor is crucial for achieving optimal accuracy. The sensor also includes various diagnostic features to detect potential errors, such as magnet loss or sensor malfunction.
