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-M1-101T as shown in Figure 12.

Figure 12 Current shunt feedback and sample timing for EVAL-M1-101T

The external amplifier gain circuit can be found in the schematics or user manual for the control board (For

example, EVAL-M1-101T see Figure 13).
