Part Number: TPS25762-Q1

Hi Expert,

Could you help me with some FW config questions when using GUI? System requirement is 65W PD source and USB3 MUX control with cable orientation GPIO output.  Attached the schematic

  1. What does this USB COMM CAPABLE (Data) mean, shall I enable this?image.png
  2. PDOs does not have 20V/3.25A which is 65W, even if in PDP config, 65W is presented.image.pngimage.png
  3. Can you help me check if this GPIO polarity is correct? image.png
  4. To enable USB3 communication, do I need to config any other GPIOs? 

Thanks,

Han

    This is for enabling the usb data capability. If this disabled, this product will be claimed as Charge only. This is not required by DP alt.

    Max FPDO is 20V/3A. PPS/AVS can give you 65W. You only set FPDOs (Fixed PDOs) in your config.

    Depending on what you need. I suggest you try it on real hardware.

    No need to config GPIO but others setting on the same page as your first question mentioned USB comm cap.

    BR,
