Hi,

Thanks for using E2E! Are you using this user guide? www.ti.com/.../slvuaj1

Power down sequence should be located on page 16.

Thanks,
Nastasha

Hi Nastasha,

Thanks for your reply~ I‘m using this user guide，but my question is when I pown down the PMIC, is there any timing requirement on the input signal and power？

Hi,

It is important to finish the power down sequence before disconnecting the PMIC. This ensures that there is no damage to the processor. We recommend you first disable the PMIC and complete power down sequence, then you can remove power from the input.

Thanks,
Nastasha
