BQ25050 power consumption

Other Parts Discussed in Thread: BQ25050

Hi,


My design includes BQ25050 and a LiIon 1 cell battery.

When the battery is not charging but is used to deliver power for the system in run time, I am wondering how much power BQ25050 is consuming. 

In this case, BQ25050 has no charge and is deconnected from the load.

Which data do I consider in the datasheet ?


Regards,

    Datasheet page 3 unders quiescent current gives:
    IBAT(PDWN) - current into IBAT pin with no input attached
    IBAT(DONE) - current into IBAT pin after charging terminated (i.e. VBAT=VBAT(REG)
    IIN(STDBY) - current into IN pin when CTRL is pulled high
    ICC - current into IN pin when VBAT >= VBATREG and no load on OUT (i.e. normal quiescent current).
