ISL88731CHRTZ

SMBus Level 2 Battery Charger

The ISL88731CHRTZ is a highly integrated Lithium-ion battery charger controller programmable over the SMBus system ( ISL88731CHRTZ ) management bus (SMBus). The ISL88731CHRTZ 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 ( ISL88731CHRTZ ) limited. High efficiency is achieved ( ISL88731CHRTZ ) with a DC/DC synchronous-rectifier buck converter, equipped with diode emulation for enhanced light load efficiency and system bus boosting prevention. The ISL88731CHRTZ charges one to four Lithium-ion series cells, and ( ISL88731CHRTZ ) delivers up to 8A charge current. Integrated MOSFET drivers and bootstrap diode result in fewer components and smallerimplementation ( ISL88731CHRTZ ) area. Low offset current-sense amplifiers provide high accuracy with 10mΩ sense resistors. The ISL88731CHRTZ provides 0.5% end-of-charge ( ISL88731CHRTZ ) battery voltage accuracy.
The ISL88731CHRTZ provides a digital output that indicates the presence of the AC adapter as well as an analog output which ( ISL88731CHRTZ ) indicates the adapter ( ISL88731CHRTZ ) current within 4% accuracy.
The ISL88731CHRTZ is available in a small 5mmx5mm 28 Ld Thin (0.8mm) QFN package. An evaluation kit is available to ( ISL88731CHRTZ ) reduce design time. The ISL88731CHRTZ is available in Pb-Free packages
