•
PCB Sensing Structure Transfer Factor [µT/A]: the transfer factor related to the sensing structure realized on
the evaluation board;
•
Sensor Sensitivity Factor [mV/A]: the target sensitivity used for calibration of the sensors on the evaluation
board;
•
Operating Voltage [V]: the analog interface voltage level of the sensors on the evaluation board;
•
Cross-Coupling Matrix: the cross coupling factors in [mV/A] between the three phases of the evaluation
board. Further information are available on the User manual [2] and by clicking on the "?" button;
•
Unique ID: unique identifier of the evaluation board. Useful for direct support by Infineon;
•
TLI4971/TLE4972 Standard buttons: to reset the external EEPROM content to default values;
•
Save to/Load from file: to save and restore the external EEPROM content;
•
Burn button: the external EEPROM content is effectively written in the external EEPROM after pressing the
"Burn" button;
•
Read button: to load the dialog box with values read from the external EEPROM. It can be used to verify
correct programming.

Temperature Readout
The Options drop down menu also offers the "Temperature Readout" menu item to read the current
sensor internal temperature from the DUT board. If the temperature readout is executing then analog output
and OCDs output are not reliable, since the sensors are put into test mode. In the figure below, the Y axis shows
the temperature in [°C] and X axis shows the number of acquired samples.
