BQ78350-R1: Shutdown Problem

Hello,

This question has been assigned and will be reviewed when possible, please attach your .log /.gg files associated with the project.

Thank you,

this is the .gg file 

All cell voltages have to be less than Shutdown Voltage and current has to be <= 0 for 255 seconds. Is there a chance that the current (e.g. with an offset error) is > 0?

Even if the current crosses over above zero for 250ms will this process reset and it will require another 255 seconds before the device shuts down.

thank you , 

Is there a way to verify if the offset caused this error?

You can log this during a test. The gauge reports the current via smbus if the host reads this. If you know that the current is <= 0 mA but the gauge reports >0 (make sure that the current deadband is set to 0mA)

thank you , 

I have a positive current reading of 1 mA. How can I resolve this issue?
