LTC1760 LOPWR trip

Hello,

I'm testing a board with three LTC1760s in parallel connected to 6 Inspired Energy NH2034HD43 packs, (4s, 2p). I set the LOPWR trip voltage to be at 11V, but I find the controllers let the batteries discharge all the way down to 9.6V where the internal battery protection kicks in and shuts off the battery output.

Any ideas what I might be missing? I had understood the LOPWR function to disable discharge when when no other power sources are present, but perhaps that is not the case. Are there any other ways to set the cutoff voltage without connecting to a dedicated SMBus host?

Thanks!

Paul
