In order to estimate the current capability of the TLE9185QX & TLE9185QX V33 shield evaluation boards, several components should be taken in account.

The attached picture shows the current path on the board.
To make an estimation the single component current limitation should be taken in considerations, refer to the below nominal values:

1) X3 Connector (20020316-G021B01LF) : max DC current 16 A

2) Inductance L1 (SPM10065VT)=1.5 uH, Isat20=25 A

3) Q2 (IPZ40N04S5L-2R8): I = 40 A

4) Half Bridge Q4 (IAUC60N04S6N031H): I= 60 A

5) Shunt resistor R33, considering a P=2 W and R=5 mΩ => I = 20 A
