Hi

We use DC/DC converter to power our Jetson
waf150-24s12w 12V 150W https://www.pduke.com/product_d/126/WAF(D)150%20Datasheet.pdf
When the Jetson is set to MAXN shortly after power on the Jetson gets shut down, we have seen this issue with more then 1 Jetson.
When powered with original power supplier it workes.

Hi, can you try removing R135 on board?

Hi

  1. Please send me the board schematics.
  2. In all the HW documents there are no component RefDes so please specify the signal name
  3. Please describe why removing R135 will solve this issue

Thanks

Please find the schematic of Xavier in DLC, there is a package of carrier board (P2822): Jetson Download Center | NVIDIA Developer

Please just try removing R135 so as to make sure if it works first.

Please refer to chapter 5.5.1, Dv/Vt Circuit Considerations, in OEM DG for this resistor design.

Hi. The carrier board schematics show that both the circuit that R135 is used in and the circuit that the TPS3808 is used in drive VIN_PWR_BAD_N. If I remove R135 won’t that still allow the TPS3808 to shutdown the system when it detects a voltage drop?
