Hi Zhang Han,

Could you share your schematics to ease understanding the problem? I have forwarded your question back to Applications engineer, since he has better backround about this case, thank you for your patience

Hello Zhang Han, Tuomo,

The AM570x datasheet specifies which power management solution can work to meet the power up and power down requirements. Using any other ICs will render the design unsupportable should any issues occur in the future.
