9.3.2.1 Configured as a DFP

When configured as a DFP, the TPS65982 detects when a cable or a UFP is attached using the C_CC1 and C_CC2 pins. When in a disconnected state, the TPS65982 monitors the voltages on these pins to determine what, if anything, is connected. See the USB Type-C Specification for more information.

Table 9-1 shows the high-level detection results. Refer to the USB Type-C Specification for more information.

RdRdDebug Accessory Mode attachedSense either C_CC pin for detach.
RaRaAudio Adapter Accessory Mode attachedSense either C_CC pin for detach.

When the TPS65982 is configured as a DFP, a current IH_CC is driven out each C_CCn pin and each pin is monitored for different states. When a UFP is attached to the pin, a pulldown resistance of Rd to GND will exist. The current IH_CC is then forced across the resistance Rd generating a voltage at the C_CCn pin.

When configured as a DFP advertising Default USB current sourcing capability, the TPS65982 applies IH_CC_USB to each C_CCn pin. When a UFP with a pulldown resistance Rd is attached, the voltage on the C_CCn pin will pull below VH_CCD_USB. The TPS65982 can also be configured as a DFP to advertise default (500 mA), 1.5 A and 3 A sourcing capabilities.

When the C_CCn pin is connected to an active cable VCONN (power to the active cable), the pulldown resistance will be different (Ra). In this case, the voltage on the C_CCn pin will pull below VH_CCA_USB/1P5/3P0 and the system will recognize the active cable.

The VH_CCD_USB/1P5/3P0 thresholds are monitored to detect a disconnection from each of these cases respectively. When a connection has been recognized and the voltage on the C_CCn pin rises above the VH_CCD_USB/1P5/3P0 threshold, the system will register a disconnection.
