I am trying to understand the cause of damage to my Jetson Orin Nano Super Developer Kit and would appreciate any guidance regarding further debugging and possible repair.

Device

Jetson Orin Nano Super Developer Kit

Component Damaged

The ESD protection IC (marked 561SY) of the third USB port appears to have burned out. After failure, the port developed a short circuit between the USB data line and ground.

Connected Peripherals

  • USB Port 4: Intel RealSense D455 camera
  • USB Port 2: Keyboard and mouse receiver dongle
  • USB Port 1: 5-inch HDMI display (powered through USB)

Power Source

The board was powered using a 6S LiPo battery connected to an LM2596 buck converter, supplying a stable 18.8–18.9 V output, which is within the supported operating range (9 V to 19 V) of the board.

Peripheral power consumption:

  • 5-inch display: ~0.5–0.6 W
  • Intel RealSense D455 camera: ~0.5–0.6 W

Incident

The issue occurred after plugging the display power cable into USB Port 1. This appears to have resulted in the burnout of the USB ESD protection IC (561SY).

Debugging Performed

To isolate the issue, the following checks were completed:

  1. Verified the power supply output, which remained stable at 18.8 V.
  2. Checked the USB power and data lines of both the camera and display for abnormalities.
  3. Tested the display and RealSense camera independently on another device, where both operated normally with stable power consumption.

Questions

  1. What could be the most likely root cause of the ESD IC failure in this situation?
  2. Could the LM2596 buck converter or startup voltage transients/spikes have contributed, even though the measured voltage remained stable?
  3. Is it possible that the display’s USB power cable introduced a fault condition (backfeeding, short, incorrect wiring, or surge) onto the USB line?
  4. What further debugging steps would you recommend to determine whether the issue is isolated to the ESD IC or if additional USB circuitry may also be damaged? For example:
    • Checking USB rail voltages
    • Measuring continuity/resistance on D+/D− lines to ground
    • Inspecting nearby components or USB controller paths
  5. If the fault is limited to the ESD protection IC, would replacing the 561SY IC typically restore functionality, or are there other components that should also be checked/replaced?

Any insights into the probable root cause, additional diagnostics, or repair recommendations would be greatly appreciated.

How does your USB port list map to the connectors in the figure below from Jetson Orin Nano Developer Kit Carrier Board Specification?

Were your battery+buck connected to the DC jack input? A description or diagram with the power and peripheral connections and the port that failed using the reference designators from the figure above would be helpful. For example, the power jack is ref des J16. For the stacked USB Type A connectors, please be specific about top or bottom connector in the x2 stack.

It’s difficult to speculate on what cause the ESD diode to fail due to a variety of factors. It could’ve been a large ESD strike, repeated smaller ESD strikes, overvoltage, etc. It sounds from question 3 like the damaged port was powering your HDMI display, so overvoltage is unlikely to be related unless a second separate power source to it was connected at the same time.

Does the Dev Kit boot up normally if you don’t use the USB port with the failed ESD diode?

You could try removing the burned part and check the signal for a short to ground. If the short disappears, try booting. If it still boots, you could try replacing the ESD diode (TI TPD4E02B04DQAR based on your photo).

To assist in your debug effort, the Jetson Orin Nano Developer Kit Carrier Board Reference Design Files package includes P3768_A04_PCB_assembly_drawing.pdf showing the component locations and the schematics in P3768_A04_Concept_schematics.pdf (shows the actual parts populated/stuffed in the design). You can map the damaged ESD diode to the corresponding USB port.
