|CC1||1||I/O||Type-C configuration channel signal 1|
|CC2||2||I/O||Type-C configuration channel signal 2|
|CURRENT_MODE||3||I||Advertise VBUS current. This 3-level input is used to control current advertisement in DFP mode or DRP mode connected as source. (See Table 2.)
L - Default Current. Pull-down to GND or leave unconnected.
M - Medium (1.5A) current. Pull-up to VDD with 500-kΩ resistor.
H - High (3.0A) current. Pull-up to VDD with 10-kΩ resistor.
|PORT||4||I|| Tri-level input pin to indicate port mode. The state of this pin is sampled when VDD is active.
H - DFP (Pull-up to VDD if DFP mode is desired)
NC - DRP (Leave unconnected if DRP mode is desired)L - UFP (Pull-down or tie to GND if UFP mode is desired)
|VBUS_DET||5||I||5- to 28-V VBUS input voltage. VBUS detection determines UFP attachment. One RVBUS external resistor required between system VBUS and VBUS_DET pin.|
|VCONN_FAULT||6||O||Open-drain output and is asserted low for tFAULT when VCONN over-current fault is detected. (See Figure 2.)|
|OUT1||7||I/O||This pin is an open drain output for communicating Type-C current mode detect when the device is in UFP mode. Default current mode detected (H); medium or high current mode detected (L). (See Table 2.)|
|OUT2||8||I/O||This pin is an open drain output for communicating Type-C current mode detect when the device is in UFP mode: default or medium current mode detected (H); high current mode detected (L). (See Table 2.)|
|ID||9||O||Open drain output; asserted low when the CC pins detect device attachment when port is a source (DFP), or dual-role (DRP) acting as source (DFP).|
|DIR||11||O||DIR of plug. This open drain output indicates the detected plug orientation: Type-C plug position 2 (H); Type-C plug position 1 (L).|
|VDD||12||P||Positive supply voltage|
