I am having the issue that the EVM I am using is drawing 1-2mA off the battery when connected.
The only connections I can see which could be doing this are the BAT input pin of the bq27520.
I am not powering the battery monitor off the battery itself. However when I do, I am also able to isolate the current which is used when I do power the battery monitor from the battery itself, so the 1-2mA current draw is not from the REGIN of the battery monitor.
The issue is that I cannot relax the battery when I have this 1-2mA draw. Overnight this will take 100's of mV off my small 550mAh battery.
The input impudence of the BAT pin is too high for this current. Did I damage the BAT pin ADC?
Thoughts? Suggestions?
