NI USB-8473 USB-CAN Repair

[strahd_von_zarovich]

Hi everyone,

My NI USB-8473 converter has been damaged (I’m not sure why).

I tried to identify the damaged part, and it appears to be the IC below. Hopefully, it’s the only damaged component. It has a “Q” marking, so it is likely a transistor array (since it has six pins).

I tried to find the exact part number but had no luck. The board has two physically isolated sections, and this IC is connected to the transformer.

The third character that looks like "h" I think
may be damaged; 3-char SMD codes seem to
be all uppercase?

67_ parts seem, many, to be 5- and 6-pin LDO
regulators from ELM.
