    Tetsuro,

    You are correct that these two chips have a challenged interface.

    Unfortunately, the only solution we have found involves adding an additional IC to the system.

    The best solution to interfacing the TPD12S016 to the AM672X is to utilize an I2C level shifter between the two chips. The TCA9517A with the A port facing the TPD12S016 will meet the very strict level requirements of the TPD12S016 interface.

    Please let me know if I can be of any further help, if this fully answers your question, please click the customer thinks resolved button or ask any further questions.

    Regards,
    Chuck
