What are the physical layer failure modes in TJA1145A that could result in the node going to bus off state. I understand all below will affect comms but not necessarily trigger a bus of state. Any comments?
CAN-H/CAN L open
CAN-H/CAN L/both short to batt
CAN-H/CAN L/both short to gnd
CAN-H short to CAN-L
Hello vipinrad,
I hope all is great with you. Thank you for using the NXP communities.
For further information about the CAN failures of the device, I do recommend reviewing the following application note.
I hope this information helps.
Regards,
David
