Hi Nxp Partner
We found that when the load current continues to be 250A, the MM9z1_638 current reading will suddenly increase (a total of 70 data. Each data transmission period is 10mS).
We also installed another shunt current sensor in the same current loop and did not find the same problem.
Can you provide firmware or hardware modification suggestions to resolve this issue? Replication is very difficult.
Br,
Mike Liang
