USB-PD MCU for Display Port Source - Power Sink

[caneralp]

Hi, we are developing a device which outputs display port over type-c and needs to sink power. Similar to Laptops when connected to hubs. The required power is less than 60W. 

Im looking a for a suitable USB-PD implementation for this purpose. Can this be achieved using the USB PD peripheral in STM32s? If so, how?

Hi @caneralp 

I'm not expert in power management, I suggest you checking the implementation provided in the demo on G0. eval STM32CubeG0 demonstration firmware - User manual section 4.3.7 Display Port demonstration.
This section 9.11. How DP does it work on EVAL-G081 demonstration.

Source code of this demo. USB PD library supports VDM (Vendor define message)
