Power delivery IC

aster94

Hello,

 

Discalaimer: I am an hobbyst, not a professional

 

I am looking for a IC that change the output from a USB-C from 5v to 12v. I was able to find a few IC (like STUSB4700 from STM but there are others) that can do this, but all the IC i found need to be connected to a master I2C. Since i run out of pins, and i would like an easier solution i would like to have a chip that can change the power delivery from the standard 5v to 12v. On aliexpress i found the IP2721 (see here: https://stackoverflow.com/questions/58666162/type-c-usb-c-trigger-set-lowest-voltage-allowed ) which is perfect for my needs but it has a chinese datasheet and doesn't seem easy t find.

 

Do you know any solution?

    Regarding your comment:

    The part you are looking for is the FUSB302BMPX

    what bit of this requirement:

    USB-C power delivery controller that can be driven only with passive components

    does that part meet? The power delivery is controlled using I2C using the part you refer to.

    I guess I missed that part in his post. My apologies.

    I take exception to your comments to "Google does not find everything, and should not be the "go-to" place...."

    and to "That does not mean anything The kid they have working there...." and extend your apology.

     

    Your comments were dismissive, with a touch of arrogance. The E14 Community ranking the two members have, reflects both their experience and knowledge level. It also demonstrates their commitment to this community. I have yet to have them offer a glib reply. Their responses carry some weight in my Rolodex of members that have the answers that I can use and their willingness to share.

     

    Maybe I should cut you some slack as your profile status indicates "Just joined the community."  After being a member for 8 years you might have learned some comment decorum.

    sorry for my comment i thought you wanted a "passive" way to do this.

  • GreatScott! (with µC)

     

  • Using the STUSB4500 you can program it with your options and it will save them. So you only need the I2C to program it once.

    Sparkfun has a board for this.

  • It took me a while to figure all this out and Im a retired engineer, lol. First you need to decide whether to use an already made board or are going to design your PCB as well. I chose the latter. Evaluation boards will be pricey for the beginner. Being I already had the ATMEL IDE and interface for all their micro controllers, I decided on their chip USB7206. Its a 100 pin QFN and handles all the power profiles up to 20VDC at 5A. Of course you have the power supply to deliver the power to start with. It just has a power rail in the chip.It is about $9.00.

    This chip carries you to a full 10gb  data transfer speed.

     

    If you do not need that speed,  the Arduino was supposed to make one with PD for the USB3.0 The micro controller above is for 3.1 gen 2. The only thing I could find on the Arduino which is called Micro PD was just some crowd funding.

     

    I'm sure that all this is too late for you but perhaps it will help others
