Sorry for late reply. Been on vacation.

Preferably I would like it to work in CC mode. But a disconnection with some sort of auto reset after a few seconds would be ok as well.

Such approach is simply wrong. Half-decent charger will have individual buck converter for each channel.

I totally agree but unfortunately that's not up to me. So this is just the way it has to be done.

The different voltages are for different devices some at 5V some at 9V. I just need the board to be easily adaptible to these voltages.
Most devices wil never draw more than 2.5A. But if you had a charger that keeps shutting down on over current it wouldn't charge at all. So CC mode is preferred.

Exe's datasheet seems like the sort of device I had in mind.

Thanks for all the help so far guys.
GigaJoe:
stm L200 - both adjustable,
or something as Lm317 current limiter, but on LT1083\4\5; no idea actually if it need linear and a power dissipation ...
