TPA3221EVM: TPA3221EVM current of PVDD behavior issue

Part Number: TPA3221EVM

Hi Team,

We have measured TPA3221EVM startup timing for Current(from power supply to PVDD), PVDD, FAULT, and OUT1_P.

We found that there is negative current at start. It was so strange and confused us. And there were several inrush current(red circle) before OUT switching.

Is it a normal behavior of this IC? We would like to learn what reason causes it.

Could you help us to explain the phenomenon of inrush current?
