We have prototyped and are considering a stacked 77910A solution to provide protection for a 16s design. The 16s battery pack in the end application can also be in parallel with other 16s battery packs. Our customer would like to be able to periodically retrieve safety information, using a host microprocessor, from each of the 16s packs in parallel.
We understand that it is not recommended to poll the status register during normal operation of the devices; however, we would like to consider a scenario in which it might be feasible to periodically (twice an hour, twice a day?) drive ZEDE to allow the host micro to read the fault status register. Can someone outline risks and potential issues associated with reading the status register during operation? False safety events? Loss of protection during polling? Polling the register after a suspected safety event has occurred? Loss of safety information during the register read? And what is the minimum time required to retrieve data from the safety status register? I have reviewed various threads and understand various issues related to noise, etc. but would like to try to understand better. I do not want to post additional details regarding our application in the forum, so would be OK taking the conversation offline.
Thanks,
