I'm noticing that on the developer board CY4532 in Powerbank configuration the P_CTRL_FET line is disconnected from the drawing you sent me recoverable some time ago at this link

Why is he disconnected? What should I take into consideration?

Hi ,

CY4532 do not use two separately path for provider and consumer path. It is only use VBUS_C_CTRL for power bank of Type-C port's provider and consumer path. You could see the VBUS_C is short to VBUS_P on power board.
