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...

When Type-C state is presented as sink port only (see Figure 5), the port is able to consume power over VBUS and must assert a pull-down resistor (Rd) on the CC pins.According to product characteristics, the behaviors on CC and VBUS can be seen in the Table 1. As a result, when...
Hi. I have a custom board design that uses USB-C in USB 2.0 mode for data and 5V power. I am aware that in order for a USB-C host to recognise the USB-C peripheral, it requires a 5.1k ohm resistor on both CC1 and CC2. I have placed these resistors on my board. When using ...
Sink Port (consumer) This port is able to consume power over VBUS (from 5 V to 20 V and up to 5 A) and must assert a pull-down resistor (Rd) on the CC pins Dual-Role Power (DRP) Port A Dual-Role Power Port (DRP) can operate as either a fixed Source or a Sink port, or ...

上拉电阻Pull-up resistor (Rp) +下拉电阻Pull-down resistor (Rd) ,通过Rp-Rd路径确定电缆连接及其方向,以及传达有关源电流能力的信息。对插头来说,正常情况下只有一个CC,通过检测CC引脚上的电压,连接线上的电压会低于未连接线上的电压,以此就可以判断连接的方向。如果是可供电的USB cable(Powered cable...
The problem lies with how different power supplies and peripherals identify each other, and quite likely in device manufacturers skimping on a few components here and there. A compliant USB-C power supply expects to see pull-down resistors on the data lines, and will thus refuse to serve powe...
The USB Type-C host can provide 5 V with either 3 A or 1.5 A, and indicates its current capabilities through pull-up resistors on both CC lines. 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 connecti...
Note that a 1 – 2 Mohm pull-down resistor is recommended for the SBU pins. Figure 1. Standard USB Connectors Are Replaceable With a USB Type-C Connector Support for USB 3.1 or USB3.2 Gen 1 (5 or 10 Gbps) is included while maintaining backward compatibility with USB 3.0 and USB 2.0....
