ADCMP350 has an internal 0.6V reference. So a 17.2K/1K divider would get you a 10.92V nominal threshold.
Over a dollar each?! No thanks, I'll pass. And if I have to use a voltage divider, I might as well use one of the cheap, ubiquitous, dedicated ICs.

ADCMP350 $1.60
Chip resistors are $0.10 each and you need three.
Total cost $1.90
TPS3847108DBVR costs $2.70 each.
TL7712A costs $1.03 each and you need 2 external resistors and 2 external capacitors. So not going to save any money going this rouge.
Might as well go with the a comparator based design since it provides more design flexibility, allowing you to adjust the desired threshold and have the output pulled up to different power rails.
If cost is an issue...there are also many similar parts, starting at $0.53 that are equivalent to the comparator option.
MCP65R41T $0.53
MIC833YM5 $0.66
