TCAN1463EVM: TCAN1463EVM SIC network between JMP6 & JMP7

Part Number: TCAN1463EVM

Hi Team,

For TCAN1463 SIC capability, is it build inside the chip as SIC Driver block?

Why the EVM board has SIC net work between JMP6 & JMP7? Is this a must for SIC function?

Could JMP6 & JMP7 & JMP3 & JMP5 be shorted at the same time or only JMP6 & JMP7     or  JMP3 & JMP5  seperately?

Thank you!
Marc

    Hi Marc,

    Yes the 1463 has an improved SIC driver, that is all built into the device.

    The SIC network is so that customers can test the performance of the SIC driver. This is the exact circuit that is used during conformance testing so a customer can verify for themselves that our SIC transceiver meets the SIC spec.

    You should not add this circuit to your designs, this circuit is just to test the device. For any SIC device you can drop it into any bus the customer already has and it will work just like before but with better performance.

    The 60 ohm load is already included in the SIC testing circuit (JMP6 and JMP7), it is R15. You should not install JMP3 and JMP5 at the same time, this will overload the CAN driver.

    Best,

    Hi Chris,

    Thanks for your confirm!

    You mentioned that "This is the exact circuit that is used during conformance testing so a customer can verify for themselves that our SIC transceiver meets the SIC spec." Could you help explain more about how to use it or any application note?

    Thank you!

    Marc,

    If you email me at c-ayoub@ti.com I can send you the conformance test for SIC testing and you see in there how they test the SIC driver and the circuit that is used.

    Best,

    Chris
