I have an interesting design challenge. I am working on a system that has multiple battery packs. The existing design uses a simple diode OR to draw power off of the pack with the highest voltage. However, the end user for this project has come back and said "we want the system to draw power off of the lowest pack, as long as the lowest pack is above some voltage threshold". I could build some FET switching array controlled by a micro that samples each pack, but figured there might be some other elegant solution using analog components, maybe not as simple as a diode OR, but similar. Any ideas?
Thanks,
Zach
