TPS65911: About application to i.MX6 Duallite

Hi team.

Did you confirm this post?
My customer is in a hurry to confirm.

Best regards,

Hello,

I do not know the power requirements for the Duallite compared to the dual unfortunately.

TPS659114 settings can be found here: https://www.ti.com/lit/pdf/swcu181 - please confirm they meet the application?

Alternatively, maybe something like TPS6521815 may be an option: https://www.ti.com/lit/an/slvaeo4/slvaeo4.pdf?ts=1618554461678 

 Hi LaRosa-san

Thank you for your support.

I received the following question from my customer.  

The startup sequence is different from the NXP PMIC PF0100. Did you check the operation by connecting i.MX6 Dual or Quad?

Thank you for your support and good information for us.

Let me ask you one more question.
Have you confirmed the operation of the following reference designs on i.MX6 Duallite?

Higa-san,

The TPS6521845 is the version of the TPS65218xx that is already programmed specifically to meet the requirements of the i.MX6 Solo/DualLite. If you choose to go with this option, no further programming is required. However, the TPS6521815 is available as the user-programmable DIY PMIC of this device, which would be used if a customer has different power sequence requirements or major block diagram changes. The document you linked above highlights how a customer would program the TPS6521815 with their desired settings if they need to go that route. 

Best,
Emily

Hi Emily-san

Thank you for your reply.

I understand.

Is it possible to change the EEPROM setting of TPS659114?

We would like to know if the sequence can be rewritten if there is a problem with the power-up sequence.

Also, is there any problem when rewriting?

Best regards,

Higa

Hello,

It is not possible to change the default programming of the TPS65911 family.
