I've designed a circuit using an MCP73871 (link below) and some lithium ion 18650 cells. I'm confused by the under-voltage lock-out (UVLO) on that chip as it's not clear (to me at least!) whether it stops devices draining the cells when they get too low, or whether it just turns itself off, and therefore requires some other way to cut the current-draw off.
Can anyone throw any light on this, and if I do need a separate low-voltage disconnect, could anyone recommend a solution please?
[EDIT] Having tested the circuit, there's 2mA draw from the "out" pins, when the supply voltage is <2.5V. Should it shut that load off or does that require a separate mosfet and control circuit/IC?
