i'm looking for a IC which is located on the "Client" (like a Phone, Tablet, ...) side of a USB QC wall adapter.
Does something like a USB-C Interface (Power Management) IC exist, which:
- can select the VBUS voltage via Quick Charge 2, 3 and 4 Interface (continuous mode)
- has a Microcontroller Interface like SPI or I2C
- optional: can monitor the VBUS voltage and or current
- optional: has a fixed 3.3V output for the Microcontroller
I'm confused by your reference to Qualcomm. Are you wanting to interface to a Qualcomm IC, if so, which one? A block diagram would be helpful.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to LeonardEllis:
i gave it a try and drew a diagram:
On the left side is a random USB Quick Charge wall Adapter. On the right side is my Device.
The Charger Interface IC on the "existing USB charger" side, would be a Qualcomm Quick Charge compatible IC (which IC doesn't matter, as long as it uses the Qualcomm QC standard).
And on my circuit is the IC I'm looking for. This IC is talking to the Charge Interface IC via D+ and D- to control the VBUS Voltage.
