VBUS_C_MON connection for CCG3PA sink-only application

[JoLu_3455101]

Hi

For a sink-only application using CCG3PA (CYPD3171), VBUS_IN is connected on the Type-C Receptacle side, but should VBUS_C_MON pin be connected to anything?

There are no sink-only examples in the datasheet, but the closest diagram (Figure 10, dual role power bank) in the datasheet shows VBUS_C_MON not connected.

VBUS_C_MON is either a no-connect for sink-only application or I can connect it to the sink side of the Consumer FETs. Which option is correct or either way works?

Thanks,
Jonathan

Hi Jonathan,

For CCG3PA sink-only application, it's fine to connect VBUS_C_MON to sink side of the Consumer FETs.
