This user's guide describes the characteristics, operation, and use of the TPS6507xEVM-430 evaluation
module (EVM). The TPS6507xEVM-430 is a fully assembled and tested platform for evaluating the
performance of the
diagrams, a printed circuit board (PCB) layout, bill of materials, and test data. Throughout this document,
the abbreviations EVM, TPS6507xEVM, and the term evaluation module are synonymous with the
TPS6507xEVM-430 unless otherwise noted.

Page 8: Connector And Test Point Descriptions
A resistor in parallel to the thermistor (NTC) is required for linearization (see the TPS6507x data sheet details). Note that the factory default EVM configuration uses a 75-kΩ resistor for linearization (R6).
