Backup Mode. Once the backup capacitor stack is charged, the system is now able to provide backup power. Charge mode and backup mode are determined by the voltage on the PFI (Power Fail Input) pin. If the V IN voltage drops such that the PFI comparator trips low, the part immediately enters backup mode (see Figure 3).

The usable energy in the single string of eight (in series) is W = 1*[(10F/8)/2*((2.7V*8)2-6V2)] = 269.1J Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs.
