The ISL6256, ISL6256A is a highly integrated battery charger controller for Li-ion/Li-ion 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 pre the ISL88731C is a highly integrated ISL88731C is a highly integrated Lithium-ion battery charger controller, programmable over the SMBus system management bus (SMBus). The ISL88731C is intended to be used in a smart battery charger (SBC) within a smart battery system (SBS) that throttles the charge power such that the current from the AC adapter is automatically limited. High efficiency is achieved with a DC/DC synchronous-rectifier buck converter, equipped with diode emulation for enhanced light load efficiency and system bus boosting prevention. The ISL88731C charges one to four Lithium-ion series cells and delivers up to 8A charge current. Integrated MOSFET drivers and bootstrap diode result in fewer components and smaller implementation areas. Low offset current-sense amplifiers provide high accuracy with 10mΩ sense resistors. The ISL88731C provides 0. 5% end-of-charge battery voltage accuracy. The ISL88731C provides a digital output that indicates the presence of the AC adapter as well as an analog output that indicates the adapter current within 4% accuracy. The ISL88731C is available in a small 5mmx5mm 28 Ld Thin (0. 8mm) QFN package. An evaluation kit is available to reduce design time. The ISL88731C is available in Pb-Free packages.
