Motor External Current feedback configuration and calculation
The current input value is product of the shunt resistance in milliohms and gain of External current sense
amplifier for EVAL-M3-102T as shown in Figure 21.

Current shunt feedback and sample timing for EVAL-M3-102T
The External Amplifier Gain circuit can be found in the schematics or User Manual for the control board (For
example, EVAL-M3-102T see Figure 22).
Figure 22 depicts IU+ current feedback sensing circuity on EVAL-M3-102T evaluation board. Please note that the
default external amplification gain is less than 1 for current sense in this evaluation board.
