Hi Team,
Can you explain to me under which conditions the Iq was measured for BQ25570?
Under electrical characteristics (page 6) it says that VIN_DC is 0V for all Iq typical characteristics.
Can you please explain this?

Stefan

Hi Stefan,
This device's internal circuitry is powered from VSTOR>1.9V not VIN_DC. So, Iq is measured by applying a voltage on VSTOR not VIN_DC.

Thank you Jeff for your fast reply on this!
One additional question:
What if Vstore=0V, Vbat>=2V, /EN=’0’, how much will it consume? Can I consider also here the 800/900nA? Will this also be taken from the battery, right?
Stefan,
If VBAT>2.1V, the PFET between VSTOR and VBAT turns on so that VBAT can power VSTOR, including the Iq of the charger itself.
