TLIN1027-Q1: We wanted to test TLIN1027DRQ1 Kline in our board

Puneeth,

No internal testing has been done to validate the protocol on our transceivers. Because the TLIN1027-Q1 does not have dominant timeout, limiting the amount of time the LIN pin can stay in the dominant state, it is compatible with K-Line systems. It is not compliant with the K-Line standard, this is the same with L-Line as well. One of the main reasons for the inability to be compliant is the integrated termination on the TLIN1027-Q1. The K-Line specification calls for 100k, but the integrated termination on the TLIN1027-Q1 is 45k.

Again though, the TLIN1027-Q1 can be used in both K-Line and L-Line systems, but care has to be taken around the system-level design.

Regards,

Eric Hackett

Dear Eric,

Thanks for the support & reply.

Please share us the recommended system level design for Kline & Lline.

Please let us know other Ti IC which supports Kline & Lline.

Thanks

Puneeth,

Unfortunately we don't have recommended system-level designs available for K-Line and L-Line, but this is good knowledge so that we can add it to our collateral development.

SN65HVDA195-Q1 will also work for K-Line, but again, this is because the lack of dominant timeout feature.

Eric Hackett
