Description of the functional blocks
This chapter covers the hardware design of the EVAL-M1-101TF in more detail. To enable users to make the
EVAL-M1-101TF evaluation board a basis for a new development or modification of their own systems, all
necessary technical data such as schematics, layout and components are also included in this chapter. Again,
please note that for almost all combinations of MADK controller boards and power boards, the configuration
files can be downloaded from the Infineon website.

Motor current feedback circuitry
2.4.1
Motor shunt configuration
Both single shunt and leg shunt topologies are supported by the EVAL-M1-101TF control board. The user needs
to ensure that the shunt configuration matches the power board hardware configuration. Please refer to the
power board User Guide for details. The shunt configuration can be changed in the option page as shown in
Figure 11.

Motor external current feedback configuration and calculation
The shunt resistance R
sh
value can be found in the schematics or User Guide for the power board (for example,
the leg shunt resistors are 250mΩ for EVAL-M1-05-065D).
