PB_IN and nRESET are connected to "Always-on supply" in datasheet P17 9.2 Functional Block Diagram.

Where this "Always-on supply" is connected to in this IC ?

The "Always-On Supply" is essentially VSYS, but it is the internal voltage that supplies VSYS (also referred to as VIN).

This voltage can be supplied by AC, USB, or BAT (BAT is the primary supply to the system), so it can range from the UVLO voltage to OVP at around 6.5V

This is on Page 12 in the Logic Levels Electrical Characteristics section of the datasheet.
