Supply for PMIC_BBATT(RTC) in AGX ORIN

Hi,
It is mentioned in the ORIN design guide as " Rechargeable cells or super
capacitors are not supported".

We are having some problems in exporting the PCBs with a battery Cell, Should we really not add a super cap like we did for Xavier NX? Is there any other alternative ways other than the coin cell?

Also, What is the typical RTC current consumption?

Thanks.

Note that unlike previous Jetson modules, this RTC back-up pin is input only. Rechargeable cells or super capacitors are not supported.

RTC current is 12 ~ 50uA.

Hi Trumany,
Thanks for the reply.

Since the RTC pin is an input, can we try powering the super cap externally as shown in the below image?

Will this work? Kindly confirm.

It looks fine.
