TPS25730: Capability for sending/receiving unstructured vendor-defined messages

Fowler Askew
Prodigy 10 points
Part Number: TPS25730

Tool/software:

I am trying to find a low-cost USB-PD IC for a UFP application capable of receiving VDMs sent by a connected power source and passing the information to an MCU or SoC. The TPS25730 datasheet says that the I2C interface is capable of "supporting communications to/from a connected device" which sounds like it could refer to a method of sending or receiving VDMs using the 25730. I just wanted to get confirmation of whether this was or was not a function included in the 25730 or another low-cost TI IC.

Thank you

    Hi Fowler,

    The TPS25730 likely does not support what you are looking for, as it's I2C interface is fairly limited.

    When you say VDMs, what specific information are you looking for?

    I would recommend checking the TPS25751 and it's TRM to see if it reports the information you are interested in.

    Thanks and Regards,

    Chris
