ZHCSIY2B July 2018 – August 2021 TPS65988
PRODUCTION DATA
When a TPS65988 port is configured as a UFP, the TPS65988 presents a pull-down resistance RD_CC on each C_CCn pin and waits for a DFP to attach and pull-up the voltage on the pin. The DFP pulls-up the C_CCn 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 pull-up applied to the C_CCn pin.
