What kind of resistor does a USB Type C connector use?
A resistor is placed on CC to mark whether a USB Type-C connector is a DFP or a UFP: DFP uses an Rp, or a pull-up resistor between CC and 5V (not Vbus, as Voltage may change using USB PD) UFP uses an Rd, or a pull-down resistor between CC and Gnd
What kind of resistor does a USB 2.0 battery pack have?
A USB 2.0 type battery pack, for example has both a type-A female and a micro-B female connector: The USB Type-C specifications (available at USB.org as “Universal Serial Bus type-C Cable and Connector Specification”) explain different resistor values for determining whether a device is sourcing or sinking current.
What are the power values for USB Type C?
The USB Type-C specification actually uses different values of resistance of Rp in order to allow the DFP to advertise its supply capabilities: 1 Default USB Power — 56kΩ pull-up 2 1.5A — 22kΩ pull-up 3 3.0A — 10kΩ pull-up More
How are Rd and RP resistors connected to CC pins?
Specific Rd and Rp resistor values connected to CC pins allow single role or dual role system configuration. Theattachment and orientation detection operations are carried out through CC lines through these resistors: a source must assert Rp pull-up resistors on both CC pins a sink must assert Rd pull-down resistors on both CC pins
What do you need to know about USB Type C?
As noted above, the USB Type-C specification describes how a Type-C upstream-facing port (UFP) applies Pull-Down resistors (R d ) on Configuration Channel pins CC1 and CC2 to signify that it is a device and the Type-C downstream-facing port (DFP) is required to have Pull-Up resistors (R p ) on CC1 and CC2.
What are the pull up values for USB Type C?
The USB Type-C specification actually uses different values of resistance of Rp in order to allow the DFP to advertise its supply capabilities: Default USB Power — 56kΩ pull-up 1.5A — 22kΩ pull-up 3.0A — 10kΩ pull-up
