How to distinguish CAN L / CAN H OPEN using TJA1442AT ?

[mumumilmil]

Hi, I'm using TJA1442AT CAN IC to Automotive HS_CAN BUS.

If CAN High or CAN Low have OPEN, TJA1442 IC detects that OPEN?

- OPEN : Ex) Circuit short/open

Thanks.

Hi,

The TJA1442AT does not detect or report an “OPEN” (disconnected) CANH or CANL condition. It has no diagnostics for open-load conditions on the bus lines.

Thanks.

Then, S32K144W can detects CAN BUS OFF?
