Hello Team,

As per the updated datasheet of AGX Xavier SoM, the power consumption of the Module is 10-30W.

But as per the absolute maximum power consumption table,

  1. SYS_VIN_HV —> 20V@5.4A
  2. SYS_VIN_MV —> 5V@6A
    together it adds up to (108W + 30W) 138W.

Please guide how to consider the typical and maximum current consumption on SYS_VIN_HV & SYS_VIN_MV rails.

That is the design threshold. The real power consumption depends on use case and is 10-30W in general.

Hi Trumany,

Thanks for your response.
By considering the maximum power mode 30W, please help to provide wattage consumption to be considered in SYS_VIN_HV and SYS_VIN_MV.

At 30W mode what is the current consumption in

  1. SYS_VIN_HV —> 12V@??A
  2. SYS_VIN_MV —> 5V@??A

That depends use case too, different use case has different power distribution.

  1. Is there any power consumption calculation tool available,
  2. What is the maximum power consumption in SYS_VIN_HV and MV considering 100% utilisation of all interfaces.

No such tool and such “maximum power consumption”. Please refer to the info of nvpmodel to understand that: Supported Modes and Power Efficiency
