We seem to be having a bit of difficulty with intermittent XREADY alarms being generated soon after wake-up. Typically within the first second after TS1 wake-up and whether or not the FETs have been activated.
I had previously noted this and attempted a workaround by ignoring alarms within the first 800ms recommended for the initial cell voltage readout in the datasheet. Alas the issue has since cropped up again after a slightly longer delay and so it seems high time to determine out the root cause.
For the record I am able to consistently reproduce the problem by reawakening the chip in less than 125ms after having transmitted a shutdown request. My vauge working theory is that restarting prior to the shutdown request having promulgated up cell bank chain or prior to bank voltage dropout somehow results in an inconsistent state.
Should a settling period after or prior to start-up suffice to avoid the issue and if so how long? May this be a symptom of a deeper issue which could crop up during active operation as well?
