    Hello Kim,

    They are both similar functions, FC has more flexibility to show with the LED functionality to a user that the full charge has been reached. TC has similar thresholds to set and can be used by the MCU to indicate when the charge should stop, it can also disable the CHGFET when set if FET Options[CHGFET] = 1. A lot of the time these flags can be set together, that's how they are at default config when VCT is set. 

    All the information is in the TRM, section 5.7 Charge and Discharge Termination Flags

    Sincerely,
