BQ34Z100-G1: PassedCharge in mAh. What is the clock accuracy

Part Number: BQ34Z100-G1

Hello, 

We are wondering about the clock accuracy of the bq34z100-G1. We couldn't find any document related to it. 

Our application uses several batteries in series. Each battery connected to a bq34z100-G1. If the clock deviates to much from one BQ to another, the SOC wouldn't be accurate. 

Can you give us some indications about that matter?

Thanksfully

    Hello,

    The clock accuracy should not be related to the SOC accuracy. The gauge uses the LFO for the ADC, but this should produce very low error because it is a delta-sigma ADC so it is integrating the charge very frequently. 

    Sincerely,
