Hi E2E Community!
I have a scenario where I need not only one backup battery source, but two backup sources.
My question is what kind of issues can be expected if connecting two TPS3619 together like illustrated below?
The primary source should be V_MAIN. IF V_MAIN fails, V_BACKUP should take over and finally if both V_MAIN and V_BACKUP fail the backup battery should take over.
Does anyone have experience with similar scenarios or alternative suggestions?
