AM572x: Confirm Power up/down sequencing

Kaka

Other Parts Discussed in Thread: TPS659037, TPS65916

Hi TI Experts,

Please let me confirm the following question.

[Question.1]
I know that AM572x datasheet provide the power supply sequence and power down sequence. But I could not find the description about time pressure for those sequences. So, can we understand that if my customer is satisfied with the sequences, they need not think about the time pressures?

If you have any questions, please let me know.
Best regards.

Hi,

Please note that AM57X processors must be used ONLY with the recommended PMICs as given here: processors.wiki.ti.com/.../AM57x_Hardware_Design_Guide

"Select from a list of complementary devices to attach to AM57x device in your system:
AM572x Power Management Device (required): TPS659037
AM571x Power Management Device (required): TPS659037 or TPS65916"

These are the only recommended PMIC solutions that meet the processor requirements and TI will not support any other power solutions.

Hi Biser,

Thank you for your response.
I know that AM57X processors must be used only with the recommended PMIC and TI will not support any other power solutions.

I will re-try to inform them to my customer.

Best regards.
