Hi, I’m trying to design a custom carrier board fot the jetson tx2, that has only a USB3.0 (for now), so I took the Concept schematic and started to eliminate the things I don’t need. So what was left was:
-400 pin connector (Pages 4,5,6)
-USB 3.0
-The fan part(page 22)
-Rail discharge
-DC Jack(page )
-5V & 3V3 Vregs (page 28)
-3V3 SLP AND 1.8V Vregs (page 29)
and the power button circuit
Is there anything else that needs to be added to make it function? like the power monitors, eeprom, etc.
And also I want to get all the component from digikey, to reduce the shipping cost, i couldn’t find a replacement for Q30 MDV3604URH, if you could tell me one.
There is a checklist in chapter 15 of OEM DG, please follow it. To only achieve USB, compare your design with checklist, including part of “Power” and “USB/PCIe/SATA Connections” in it.
For replacement of Q30, I’m afraid that you have to search on digikey with its characters.
Any power P-channel MOSFET with 20A or better capacity can be used. Almost all of them have the same pin-out too, so they are typically interchangeable on an already-made PCB.
I quite like STL62P3LLH6. It has lower resistance than the one you indicate, and it’s only a buck in singles. I believe it would work very well as a replacement for you.
