The Source supplies pull-up resistors (Rp) on CC1 and CC2 and monitors both to detect a Sink. The presence of an Rd pull-down resistor on either pin indicates that a Sink is being attached. The value of Rp indicates the initial USB Type-C Current level supported by the host. The Sou...

Devices utilizing USB C must include a 5.1K pull-down resistor Rd on the CC line for devices with only a USB Type-C connection. For devices with a Type-C receptacle, Rd should be advertised on both CC1 and CC2 lines. What is the process for USB-C devices to manage VBUS...
Source Port (provider) This port is able to supply power over VBUS (5 V to 20 V and up to 5 A), and must assert a pull-up resistor (Rp) resistor on the configuration channel (CC) pins Sink Port (consumer) This port is able to consume power over VBUS (from 5 V to 20 V and ...
Figure 5. USB PD over CC pins The receptacle is specified up to 5 A current but Type-C cables are rated for 3 A. So, for current higher than 3 A, the electronic marking of the cable is mandatory. AN4871 - Rev 3 page 5/32 1.3 1.3.1 1.3.1.1 AN4871 Differential lines Differential...
NX20P0407是一款单芯片USB Type-C端口保护器件,为CC1/CC2和SBU1/SBU2引脚提供28V的VBUS过压保护。USB Type-C通过电源传输协议允许VBUS电压增加到20V。 由于Type-C连接器的接触引脚间距比微型USB连接器小25%,因此在连接器弯曲和滑动时可能会导致CC1/2和SBU1/2引脚与VBUS短路。湿气或细小的灰尘也可能导致20V的VB...

USB-A to USB-C cables are the least interesting. They’re equivalent to a microUSB to USB-A cable, except there’s a resistor on the USB-C plug, connected from VBUS to one of the CC pins. That’s it. The cable contains four conductors, there’s really not much new. Save these ...

To convert an existing USB 2.0 host to USB Type-C, Vbus for each port must be switchable. Additionally, pull-up resistor(s) and the capability to detect one of the device pull-down resistors must be added. Some host PHYs can use the VbusValid detector for detecting devices. Some host ...
