SLVSD02E March 2015 – August 2021 TPS65982
When the TPS65982 is configured as a UFP, the TPS65982 presents a pulldown resistance RD_CC on each C_CCn pin and waits for a DFP to attach and pullup the voltage on the pin. The DFP will pullup the C_CC pin by applying either a resistance or a current. The UFP detects an attachment by the presence of VBUS. The UFP determines the advertised current from the DFP by the pullup applied to the C_CCn pin.
