Provider Load Switch
VBUS Regulator CCG6DF and CCG6SF devices have an integrated provider load CCG6DF and CCG6SF devices can either be powered by VSYS switch with the following functions. or VBUS power supplies. There is one VBUS per port. Hence the CCG6DF device can be powered by either VBUS (Port0 or Undervoltage and Overvoltage Protection on VBUS Port1) or VSYS. A regulator operating on these power supplies CCG6DF and CCG6SF devices implement an under- derives the chip operating supply. When both power supplies are voltage/overvoltage (UVOV) detection circuit for the VBUS present, VSYS always takes priority over VBUS supplies. In supply. The thresholds for both OCP and UVOV are program- absence of VSYS, the regulator powers the chip from VBUS. mable. Gate Driver for VBUS NFET High-side Current Sense Amplifier for VBUS CCG6DF and CCG6SF devices have integrated gate drivers to CCG6DF and CCG6SF devices support the programmable drive external NFETs on the VBUS consumer path. The provider threshold VBUS current sensing through VBUS provider path. NFETs are integrated. The consumer side supports only the External resistor (5 mΩ) placed in VBUS provider path external NFET driver and these NFETs must be capable of connecting to the chip, the drop across this resistor is monitored supporting ±VBUS_MAX VGS. CCG6DF and CCG6SF must be to sense the magnitude of current. in active mode to enable the consumer-side NGDO. VBUS Reverse Current Protection VBUS Tolerant SBU and CC Lines CCG6DF and CCG6SF devices restrict reverse current to zero CCG6DF and CCG6SF devices support VBUS tolerant SBU and on the VBUS provider path when the Type-C VBUS is greater CC lines. In case of SBU/CC short to VBUS through connectors, than VIN (provider voltage before the VBUS NFET). these lines are protected internally. Accidental shorts may occur because the SBU/CC pins are placed next to the VBUS pins in VBUS Short Circuit Protection the USB Type-C connector. A Power Delivery controller without the high-voltage VBUS short protection will be damaged in the CCG6DF and CCG6SF devices have a VBUS short circuit protection function of which the SCP threshold is programmable. event of such accidental shorts. When overvoltage is detected Whenever current through the VBUS Provider Load Switch on the SBU/CC lines, the internal protection circuit will turn off the connection between the Type-C connector and the rest of the exceeds the programmed threshold, the SCP gets triggered instantly and turns off the VBUS provider path within a short device. duration. VBUS Discharge CCG6DF and CCG6SF devices support high-voltage (21.5 V) VBUS discharge circuitry inside. After cable removal detection, the chips discharge the residual charge and bring the floating VBUS to less than 0.8 V.

In the top layer, two CC pads are shorted using 0.2mm trace width and connected to other layers through one via. The capacitors are placed on bottom layer and are routed to the Type-C Connecto... Rsense and Capacitor Connections for Provider VBUS The differential signal from Rsense should be length matched. The capacitor for Provider VBUS should be as close as possible to the Rsense and connected using copper shape. Figure 19 and Figure 20 show routing for Rsense.
