Highly Integrated Battery Charger Controller for Notebook Computers

The ISL6251, ISL6251A is a highly integrated battery charger  controller for Li-Ion/Li-Ion polymer batteries and NiMH  batteries. High efficiency is achieved by a synchronous buck  topology and the use of a MOSFET, instead of a diode, for  selecting power from the adapter or battery. The low side  MOSFET emulates a diode at light loads to improve the light  load efficiency and prevent system bus boosting. The constant output voltage can be selected for 2, 3 and 4  series Li-Ion cells with 0.5% accuracy over-temperature. It can  be also programmed between  4.2V+5%/cell and 4.2V-5%/cell  to optimize battery capacity.  When supplying the load and  battery charger simultaneously, the input current limit for the  AC adapter is programmable to within 3% accuracy to avoid  overloading the AC adapter, and  to allow the system to make  efficient use of available adapter power for charging. It also  has a wide range of programmable charging current. The  ISL6251, ISL6251A provides outputs that are used to monitor  the current drawn from the AC  adapter, and monitor for the  presence of an AC adapter. The ISL6251, ISL6251A  automatically transitions from  regulating current mode to  regulating voltage mode.
