AM625: AM625 compatible PMIC options

Sahil Nayak

Part Number: AM625
Other Parts Discussed in Thread: TPS6522005-EP

Tool/software:

Hi Team,

Initially, we were looking to use the TPS6521903 PMIC with the AM625 processor in our system. However, we require the storage temperature to be -55°C ~ 85°C, and the mentioned PMIC part doesn't support the lower side limit of the temperature. 

1. Could you please confirm if the TPS6521903 part would be able to meet the -55°C lower limit storage temperature requirement?

If not, we have found one another PMIC TPS6522005-EP that meets our storage temperature requirements.

2. Could you please confirm if this PMIC TPS6522005-EP is compatible with the AM625 processor?

Thanks & Regards,
Sahil Nayak

    Hi Team,

    We are looking for a quick response on this, so we can have further clarity to decide on the PMIC.

    Hi Sahil, 

    Apologies for the delay, this thread was incorrectly assigned to the wrong team earlier. 

    1. As stated in the datasheet, unfortunately TPS6521903 is only qualified for -40°C lower limit storage temperature. This will not meet the -55°C requirement. 

    2. TPS6522005-EP is the extended performance device within the same family, this is qualified for -65°C lower limit.

    Yes, this device can be compatible with AM625. TPS6522005-EP is a user-programmable device, so the settings come as a blank configuration.
    The configuration can mirror that of the TPS6521903 configurations to be compatible with AM625.
    NVM programming details can be found in this document: https://www.ti.com/lit/pdf/SLVUCM5

    Let me know if you have any further questions about this device family or regarding the programming steps.

    Best Regards, 
    Sarah
