From the comments on our earlier standalone Linear Li-Ion battery charger with thermal regulation in ThinSOT app note post, Jan writes:
Nice chip, indeed. Unfortunately not easy to find stocked – here I can get it only from Farnell (5 euro + VAT a pop) or Digikey ($3/pc + VAT + import duties).
I would rather use something like MCP73831 – costs about 50 cents, same sort of package, but only 500mA max charging current. Which isn’t too big deal in most cases – USB can only deliver 500mA max by default …
