I'm having trouble reading average current from the BQ27421. My system consumption is somewhere around 8-10mA, and a lot of the time it outputs the correct value. For long stretches though, it outputs 0mA for average consumption. Sometimes it will switch back to the correct reading, and sometimes not. (A reset usually fixes it though).
I thought that maybe the BQ27421 automatically entering sleep mode had to do with it so I disabled sleep mode in the OpConfig register, but that didn't do anything. Battery voltage and state of charge always give the correct values, only average current seems to be off.
Has anyone else seen this before? Is there a fix?
Thanks,
Ben
