Hello there,

BR,

Hello there,

  Please refer to this document "TPS659037 User's Guide to Power AM574x, AM572x, and AM571x (Rev. F)" for what you're looking for.

  BTW, TI doesn't recommend to use TPS659037 or TPS65916 for any new design. 

Thanks!

Phil

Helllo Phil,

Thank you for your answer.

However, it wasn't the answer I was hoping for.

[About answer]
・It seems that there are no specific regulations in the materials you sent. where should I refer?

[About Not Recommended for New design]
・I understand that there is a Hirel product for the AM5718 and that it will be supplied stably for a long period of time.

　Does it mean that the PMIC for AM5718 is Not Recomend for New design?

・Will there be a PMIC for the AM5718-HIREL in the future?

I am sorry to bother you, but please answer me.

Best Regards

Hello there,

  Can you tell more details about what you're looking for "specific regulations"? 

  I need more time to check with my colleagues for replacement PMICs for the AM5718-HIREL in the future and reply you whenever I get any answers. 

Thanks!

Phil

Helllo Phil,

Thank you for your prompt reply.

I'm sorry I didn't explain enough.

The number I want to know is the time of the red line below.

Helllo Phil,

I checked the link but didn't seem to get an answer.

REGEN1 is the output signal of PMIC, isn't it?

The model number of the PMIC is also different, but is it the same design?

Where is Time from input of On Request to output of SMPS4 written?

Where can I find the relevant times for ACT2OFF Sequences?

I apologize for the inconvenience, but please check and reply.

Best Regards,

Hello there,

  I'm trying to check with all other Apps who supported the devices before, and so far no one has response. I'll let you know whenever I get answer. 

Thanks!

Phil

Helllo Phil,
