BQ35100EVM-795: Whats the update frequency required in Accumulator mode?

Part Number: BQ35100EVM-795
Other Parts Discussed in Thread: BQ35100

Tool/software:

Whats the update frequency required in Accumulator mode? 

That is how often is the GE ON->guage start->accumulator read->gauge stop-> GE OFF  cycle required. 

From the data sheet it appears like it's '30 minutes' - Is that correct? Or can it sit indefinitely without waking, continuously measuring charge while GE OFF?

    Hi,

    The bq35100 device measures and updates cell voltage, cell temperature, and load current every 1 s and begins accumulating after GAUGE_START is received.

    Evan,

    Thats not what I'm asking. We are building a low-power application. What I'm asking is given the cycle above (wake-measure-sleep)-How often do I have to wake up and take measurements so that the AccumulatedCapacity stays accurate. Again the datasheet reference 30 minutes. In the first page it mentions 8 hours for some modes. 

    I'm just looking for confirmation, from an expert what the frequency is. Make sense?

    Hi,

    That was unclear from your original post, every 30 minutes is required.
