Hardware description of EVAL-M1-101T

Figure 13 depicts IU+ current feedback sensing circuity on EVAL-M1-101T evaluation board. Please note that the

default external amplification gain is less than 1 for current sense in this evaluation board.

Based on this calculation, the current input for the MADK combination of EVAL-M1-101T and EVAL-M1-CM610N3

is 83.3 mV/A, and for the combination of EVAL-M1-101T and EVAL-M1-05-65D it is 208.3 mV/A. Please use same

procedure to calculate the current input for other combinations of MADK boards and enter it into MCEWizard.
