- Why are CC1 and CC2 only connected to USB-C?
So is CC2 and CC1 going low or high? – euraad The specification listed above has the following in section 4 5 1 2 1 Detecting a Valid Source-to-Sink Connection: Which means on the power sink: One of CC1 or CC2 will be high The other CCx signal will be low Which CCx pin is high and which is low indicates the orientation of the USB Type-C cable
- usb device - USB Type-C: Are CC1 and CC2 interchangeable? - Electrical . . .
USB Type-C cables (and legacy cables) have only one CC wire The wire indicates which Rx Tx lanes to use When connected, if CC1 is "active", it means "normal" plug, and the FUSB302 chip will inform the I2C host master over I2C interface about plug orientation (and port capability of the other side)
- circuit design - Is it sufficient to put 5. 1k pulldowns on CC1 and CC2 . . .
Read the voltage on CC2, if it is above 1 31V, you can draw 3A @5V (see USB Type-C Spec R2 0 - August 2019 page 241) Communicate with the charger with active USB PD (over either CC1 or CC2) You can get up to the chargers limit of 5A@48V; Note that the standard says any USB C source on a multiport charger should at least support 1 5A @ 5V (page
- CC1 and CC2 when connecting USB C to USB 3. 0, is this pulldown network . . .
My problem is the CC1 and CC2 logic I read about the pullup and pulldown networks needed for UFPs and DFPs for USB C Some sources: , So, I connected CC1 to a 5 1k resistor and connected that to ground I did the same for CC2
- Beside connected to pulldown resistor on CC1 CC2, does it need to . . .
I'm looking to use USB C in my schematic but instead of using USB3 1 data line I would like to use USB2 0 data line This device is on the receiving end and already have internal power so do not need power from the host My question would be beside connecting to pull down resistor, do I need to connect CC1 and CC2 to microprocessor?
- USB-C CC1 CC2 Pins - Electrical Engineering Stack Exchange
"Please note that I've only populated CC2 <> GND in my setup Due to this reason you must plug the USB-C cable in the right orientation If you plug it in the wrong orientation, the PWM output will be at 100% or in other words at 10 V "
- USB-C passthrough (including CC line) not making connection
Pins CC1 and CC2 of each Output receptacle are joined, and then switched through the rotary switch and connected to the CC1 and CC2 pins of the input receptacle A common ground plane is shared between all three receptacles and isn't switched by the rotary switch
- usb c - Which way does power flow on USB type-c if CC1 and CC2 are not . . .
Unlike the classic USB Type-A-B connectivity (where the USB host always have VBUS on), the default state of VBUS power on Type-C connector is always OFF until the Type-C receptacle sees any (valid) signaling on CC lines
