Other Parts Discussed in Thread: TLIN1027-Q1

Hi,
We are in the process of designing OBD. Do you have any controller which supports all the protocols stated below:
SAEJ1850
ISO14230
ISO 9141 - 2
ISO 15765 CAN

Please share your thoughts on following queries:
1.Do you need a dedicated module on controller other than transceiver to Interface J1850 (VPW AND PWM)?
2.Can we use normal SCI/UART for K line and L Line protocol.
3.Is there any thing such as K Line UART like (CAN TX and RX - CAN DEDICATED UART), is dedicated UART available for this protocol.
4.Please suggest suitable transceivers if you have.
5.Please share reference designs and App notes with the Infor regarding the designing of OBD Protocols.

Hi Amal,

TI does not offer such a controller.

Thanks,

Arun

Hello,

Thanks for your questions!

From the standpoint of a transceiver, we do have a LIN transceiver device that provides several standard protocols, but may not match all of the above. This device is TLIN1027-Q1. See https://www.ti.com/product/TLIN1027-Q1#design-development. There is an associated evaluation board for this device as well.

Please see the following E2E thread which also touches on a CAN transceiver for such an application: https://e2e.ti.com/support/microcontrollers/other/f/908/t/893518

If these resources are insufficient, please let me know so I can connect you with a LIN K-Line expert regarding this!

Regards,

Vince
