In "ALWAYS ON" mode, what is the accuracy of the 250 msec Alert pin?
We found that it's accuracy was off by about 2%.
This was tested by counting the Alert pin pulses over a one hour interval and comparing it to an Atomic clock.
BQ76930 DOC REF:
7.3.1.1.3 16-Bit CC
In ALWAYS ON mode, the CC runs at 100%, gathering a fresh reading every 250 ms. The conclusion of each reading sets the CC_READY bit, which toggles the ALERT pin high to inform the microcontroller that a new reading is available. To enable Always On mode, set [CC_EN] = 1.
