ISL6291
feature of the ISL6291 guarantees safe operation when the printed circuit board space is limited for thermal dissipation. The charger reduces the charge current automatically, as the internal temperature rises above a preset level, to prevent further temperature rise. When the wall adapter is not present, the ISL6291 draws less than 1µA current from the battery. Two logic outputs provide the charging status and fault information, and an easy interface to system logic. A V2P8 pin outputs a 2.8V reference voltage that can be used to bias other circuits, or as an indication for the adapter presence. The ISL6291 is packed in a thermally enhanced 5x5 QFN package. See the Technical Brief TB389 given in the Related Literature for more information related to the package.
