XENSIV™ TLE4972 current sensor user manual

The user manual describes the output modes and sensing principle in Chapter 1 and the detailed technical aspects of the device required for integration in a system in Chapter 2. The internal block diagram and the typical application circuit are available in the product datasheet [1]. TLE4972 features an integrated EEPROM enabling high flexibility at system level. The document provides a description of the available interface commands in Chapter 3. Measurement range, as well as OCD thresholds and output mode can be programmed by the user. The full set of programmable settings is explained in Chapter 4.2. Initial errors due to part to part variation and misalignment with respect to the current rail can be canceled out through a single point, room temperature calibration. Details about calibration concept and error components are reported in Chapter 6. The device is intrinsically robust against stray fields thanks to the differential sensing technology, and crosstalk between nearby phases in multi-phase systems can be compensated at system level as explained in Chapter 7. Deviation of behavior from datasheet specifications when the ratiometricity settings are re-programmed is explained in Chapter 8.
