DATASHEET ISL6253 Highly Integrated Battery Charger for Notebook Computers FN9117 Rev.2.00 August 2004 The ISL6253 is a highly integrated battery charger controller for Li-Ion/Li-Polymer 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 or 4 series Li-Ion cells with 0.5% accuracy over temperature. It can also be programmed between 4.2V +5% per cell and 4.2V -5% per cell to optimize battery capacity.
