TLE4972 Current sensor programmer
User guide
About this document
This document describes feature set, hardware and software layers of the Infineon Current Sensor Programmer.
Scope and purpose
The purpose of this document is to guide the user in the programming, calibration and general evaluation of
compatible TLE4972 sensing boards using the Infineon Current Sensor Programmer.
Intended audience
This document is written for TLE4972 users who are dealing with the implementation of the product in the
system.
Evaluation Board
Infineon's magnetic current sensor evaluation kit consists of the Current Sensor Programmer board, USB
cable and evaluation board connection cable. The programmer GUI along with Current Sensor Programmer
board can be used to evaluate, program and calibrate Infineon's set of evaluation boards or a customized PCB
setup. The programmer board is to be used by the customer solely for the purpose of evaluation and testing. It
is not a commercialized product and shall not be used for series production. The programmer board is thus not
intended to meet any industrial specifications and the recommended operating ambient temperature is 80°C.
The following key aspects are discussed in this document:
•
Programmer board and evaluation board order information;
•
Programmer board and GUI description;
•
Programmer board ELV and SELV isolation scheme;
•
GUI installation procedure;
•
Typical application setup with and without Infineon evaluation boards;
•
GUI operation with and without Infineon evaluation boards;
•
Easy programming of current sensor parameters such as operating mode, sensitivity, overcurrent threshold
and deglitch filtering time;
•
Internal signals readout (e.g. internal temperature);
•
Crosstalk compensation procedure;
•
Calibration procedure.

Page 17: Optional External Power Supply Connection
Optional external power supply connection The programmer board typically draws about 350 mA when connected to the TLE4972 evaluation boards. This current can be delivered via the USB port of a PC, which is usually specified to deliver up to 500 mA. A reverse current protection diode ensures safe operation and protects the USB port of the Laptop/PC in case power is provided through the measurement header at the same time. -
