PMIC used in Jetson Xavier NX


The datasheet of the Jetson Xavier NX mentions “Details of the types of backup cells that optionally
can be connected are found in the PMIC manufacturer’s data sheet.” However they do not provide any part number for the PMIC used. Where can I find this information ?

The PMIC is MAX20024. The listed three cells are supported.

I am unable to find any datasheet for MAX20024 online. I am looking for clarification on the protection circuits for the compliance of UL standards that require a series resistor with the battery to limit charge current for the coin cell being used for RTC backup. I want know if there is any protection built into this IC.
I would really appreciate any help related to this.

The charging current can be set by PMIC.

Hi,
Please refer to the device tree for configuring PMIC:
