Tool/software:
Greetings,
We are using BQ24610 IC in our design for 3S1P Li-ion battery.
We are looking into the consumption of this IC when the device is in off-state. When measured between the BTST and Battery positive wire, when the device is unplugged and in off state, the current consumed measured is 76uA. We are figuring out whether there are any other consumptions in the IC, other than the data provided in the spec sheet "Energy star low quiescent current Iq – < 15-μA Off-state battery discharge current"
The Circuit in our device is similar to "Figure 20. System Schematic with Power Path" in the BQ24610 datasheet with slight modification to below pins based on requirement
CTTC = 0.1uF to GND
Another NTC connected parallel to R8 for setting fats charge current. Fast charge current is dependent on the NTC thermistor values as it relates to the DUT external ambient.
R4, R6, R8 values are modified for Setting Fast-charge and Pre-charge current.
C1 = 1uF
R9 = 9.1KOhms
R10 = 191kOhms
Can you be able to help us figure out where the consumption could be?
Kind Regards
