Hello,
Are there any single cell gauges capable of distinguishing between > 500 uA for NORMAL current and <50 uA for SLEEP current?
I have a very small (< 75 mAh) battery. Gauges like bq27621-G1 and bq27421-G1 seem like a good fit, except it appears that the Sleep Current for these cannot be below 1 mA. In this use case, the system spends a lot of time in an 'idle mode' that draws between 0.5 and 1.5 mA, and I'd like to keep the gauge active in this state to keep the state-of-charge as accurate as possible.
From bq27421-G1 TRM p30:
Thanks,
Jonathan
