Are CCG devices pre-programmed at factory with power profiles to negotiate Power Delivery contracts in either UFP or DFP roles?

Are the factory delivered profiles defined in the Datasheet or an Application Note?

I'm specifically interested in a CCG3PA factory set to DRP = CYPD3171-24LQXQ.

I would like to know in general how to determine how any CCG device set for any role will start up on a new product.

I'm guessing each device starts with either no Power Profile or a 5V, 1A  profile to accept the default power configuration. I'm sure this is clearly documented somewhere I've neglected to look.

Will the CYPD3177 communicate on a 1.8V I2C bus?  The datasheet does not specify a voltage range for the HPI, and neither does the HPI specification document.  Reference designs show 3.3V I2C bus.

I have a UFP (sink) design that uses the CCG6 (CYPD6125) that connects to a LCD and to a HX3 (USB 2&3) hub. I need to configure the CCG6 to connect in type-c DisplayPort alt mode. When trying to enter the DisplayPort alt mode the board sends a "Responder NAK".

Planning to use CCG3PA for a power-sink (consumer role) only.
The board has no other power-sources nor batteries at the time of an type-c ac/dc being plugged in.

1.)
Can't find anything in the official CCG3PA datasheet that states what VBUS_P_CTRL's default state is.
Since the regulator for the CCG's VDDD rail will be post the 'consumer fet', it would be great with some input if this cold-booting ("dead battery") state is supported. 

2.)
Let's assume we would have a local power-source, so that VDDD would already be powered with a 3.3V rail.
Are there more details available on how to handle the fact that VDDD is also an output/regulator coming from the CCG3PA once it sees VBUS. I can see a diode in the block-level schematic in the datasheet but some more details would be great.

Thanks 

I have a UFP (sink) design that uses the CCG6 (CYPD6125) that connects to a LCD and to a HX3 (USB 2&3) hub. I need to configure the CCG6 to connect in type-c DisplayPort alt mode. This should be pin assignment D (2 lane DisplayPort and 2 for USB superspeed). I have the board getting PD power just find but the PD contract stalls before it can enter into the DisplayPort alt mode. I'm pretty sure I don't have the config correct.

For testing I'm connected to the CCG3 development board.

Wanted to use CCG5, 6 or 7 series, but seems almost all CCG-series are 0 stock globally.

Can Infineon please let us know what parts will be stocked again soon.

thanks david

Hi I am planning to use CYPD3171-24LQXQ in my design and this is for QC operation. In the datasheet it is given that it supports QC4.0. Just want to know whether it supports all QC modes with both source and sink capability? Because i am in a confusion after going through the QC related answers in the forrum.

Please let me know

Thanks and Regards

I am implementing a design that follows the CYUSB4357 reference design from the evaluation board.  The buck/boost switcher controllers NCP81239MNTXG and NCP81239AMNTXG are in short supply. I was able to get a good quantity of NCP81239MNTXG, but cannot find any of the NCP81239AMNTXG until November.  I am considering loading the NCP81239MNTXG in place of the NCP81239AMNTXG, but it will have an I2C address that clashes with the NCP81239MNTXG.  If I cut the I2C signals that were going to the NCP81239AMNTXG, what will the hub software do if it can't communicate with that part?
