Hi, I am trying to minimize part count and I plan to use the CYPD3123 for PD negotiation and as the main system microcontroller.  I have a design using BQ25713 which already has FETs to control VBUS into the system and OTG out.  I have a design using the CCG2, but the customer will likely require USB firmware updates to the microcontroller.  So I am switching over to the CYPD3123.  Is there any additional concerns for CCG3 function if I rely on the CYPD3123 controlling the BQ25713 instead of the recommended C and P FETs.

Hello Chris,

The application where CCG3 is used seems fine . Please refer to the CCG3 FAQs KBA which addresses questions on VBUS_P_CTRL, VBUS_C_CTRL and dead battery termination(Rd_db).

Best Regards,

Yatheesh
