Behavior without VDDD for CCG3PA

[TeMa_2997106]

It uses CCG3PA as DFP.

If the opposite device is inserted without VDDD,

(≈ voltage is applied to VBUS_C_MON_DISCHARGE)

How does CCG3PA work?

Does CCG3PA start to operate with power supplied?

Open ProviderFET because it has VBUS?

If so, what would be the workaround?

The FET is unintentionally turned on, but I want to avoid it.

Thanks,

Tetsuo

Hi Tetsuo,

CCG3PA can operate from two possible external supply sources: VBUS_IN_DISCHARGE (3.0 V–24.5 V) or VDDD (2.7 V–5.5 V). It is impossible to powered by VBUS_C_MON. So that CCG3PA will not work.
