BQ25601: Need to know the Quiescent current value for the BQ25601.

Hebbar Sudarshan
Prodigy 40 points
Part Number: BQ25601

Tool/software:

Dear Team,

1. We are observing 1.4 mA across 5V input side of battery charger IC and 1.1mA across output side of battery charger IC. 

a) Let me know what will be the quiescent current value for the BQ25601RTWR battery charger IC with 5V input supply with no battery connected?

b) What is the quiescent current value when there is only battery connected (Full charged VBAT = 4.2V)?

c) What is the quiescent current value for BQ25601RTWR battery charger IC with 5V input supply with fully charged battery connected?

d) What is the quiescent current value for BQ25601RTWR battery charger IC with 5V input supply with battery connected(Charging state = 3.9V)?

Regards,

    Hi Hebbar,

    On one unit:

    a) With 5V input and no battery and charge disabled the IQ is 2.20mA. This seems to agree with a similar test condition for VBUS of 12V greater than battery voltage.

    b) With 4.2V battery and 4.199V charge voltage regulation the battery IQ is 51uA. This seems to agree with a similar test condition for VBAT at 4.5V with no VBUS and BATFET enabled.

    c) With 5V input and 4.2V battery and 4.199V charge voltage regulation the battery IQ is 100uA and the VBUS IQ is 2.0mA.

    d) With a battery charging, the IQ will be determined by the register settings and applied voltage.

    Regards,
