These chips (Li-Ion charger + buck regulator) have a /CHRG open-drain output, that can indicate end-of-charge or various error states, and is documented as being usable for LED output. However, the only relevant spec given is V(OL) at 5mA - I can't find any specification or graph that applies at higher currents. My intended application would be used exclusively outdoors, so I want that LED to be as bright as possible - could this pin safely sink 15 or 20 mA?
