TPS65219: TPS65219

Intellectual 560 points
Part Number: TPS65219


Hi TI

According the review result , TI feedback the "PTPS6521920WRHB#Q1" PMIC can't support the 0.85V Core voltage which will lead to not support USB backup boot option.

As the USB backup boot option allows only 0.85v core voltage.

Which part number can pin to pin compatiable with "PTPS6521920WRHB#Q1" ? we need USB backup boot mode for first time bring up .

    Hi,

    Thank You for using E2E! The TPS65219-Q1 PMIC supports DVS and its output voltages can be configured/re-programmed. Since the AM62 processor doesn't support DVS, then having a different voltage on Buck1 will require a new orderable part number with similar NVM settings as the TPS6521920W-Q1 but with Buck1 configured to output 0.85V.

    A new orderable requires approval from our marketing team so I'll discuss this with them and provide an update within 24Hrs. 

    Thanks,

    Brenda

    Hi,

    Just wanted to provide an update here. Our marketing engineer is discussing the potential new NVM config with the FAE who is supporting this opportunity. I'll follow up with an update within 24-48hrs

    Thanks,

    Brenda

    Hi Brenda,

    Our customer wants to use a PMIC supporting 0.85V VDD_CORE. Could you please help to check if TPS6521904 can meet the requirements and is orderable?

    Hi Xingyu,

    The TPS6521904 you are referring to is a non-automotive OPN. For automotive applications, like our marketing engineer mentioned, we will need a new OPN with settings similar to the TPS6521920W-Q1 but with Buck1 configured to output 0.85V. 

    Thanks,

    Brenda

    We are waiting for approval from our marketing team to create the new NVM for the 0.85V use case.

    Thanks,

    Hi Jingcheng,

    Thanks for your patience! The FAE and sales that are assigned to this opportunity are discussing about the new NVM with our marketing team. They will communicate with you by email. In the meantime, I would recommend designing the prototype PCB compatible with the 0.75V and 0.85V NVMs. 

    • When using 0.75V:  VDD_CORE is supplied by Buck1 (0.75V) and VDDR_CORE is supplied by LDO2 (0.85V).

    • When using 0.85V:  VDD_CORE and VDDR_CORE are both supplied by the same PMIC rail (Buck1 = 0.85V)

    You can add 0Ohm resistors that would allow to disconnect VDDR_CORE from PMIC LDO2 and connect it to Buck1 when using the 0.85V NVM. Let us know if you have any technical questions and we will be happy to help!

    Thanks,

    Brenda
