Dear NVidia Team
In the Design Guide of the Jetson Nano, Figure 5-5, it is written that SHUTDONW_REQ* must always be serviced by the carrier board, even in cases of sudden power loss. However, in the schematic of the Jetson Nano, there is nothing servicing this SHUTDOWN_REQ* signal from the carrier board to the Module like a voltage supervisor or similar. Do we understand something wrong or how is this requirement met?
We use the Power ON/OFF Logic also for a Xavier NX Design. There the DevKit has an additional DC Jack Unplug circuit and an optional voltage supervisor.
So we would like to know what is necessary to prevent problems with sudden power loss for a design with a Jetson Nano or a Jetson XavierNX.
Thank you for your help.
