LTC4124 VCC(Pin 1) output

Hallo,

I would like to use the LTC4124 for a prototype device where the battery(LIR1620) is fix installed. I was wondering if the VCC output power from the battery if no voltage is supplied on ACIN(Pin11) and DCIN(Pin 12). If not how would you recommend to use the LTC4124 as part of a device and not as "charger only"?

best regards
