BQ76942: DASTATUS6 accumCharge stays at -1

Hi Robin,

Do you have a current flowing when you are reading this value? 

Regards,

Matt

Yes, with and without current, the variable stays at -1...

Hi Robin,

How much current is being applied (and which direction)? Is the Accumulated Charge time increasing?

Hi Matt, 

I applied between -200mA and +5A. Yes, the accumulated charge time increases, as long as all the fields in the DASTATUS6... but not the accumulated charge. Current is also correct.

Hi Robin,

What is your setting for User_Amps in the DA Config register? Are you sure you are waiting long enough to see the Accumulated Charge increment? If User_amps are set to 1 mA for example, it should increment ~ every 20 seconds for a 200mA discharge current.

Hi Matt

yes I am using the mA unit. I waited enough and also tried with currents up to 5A.

are there any reasons that this accumulated charge could stay blocked but with an accumulated charge time increasing ?
