ISL88731HRZ规格书详情
The ISL88731 is a highly integrated Lithium-ion battery charger
controller, programmable over the SMBus system management
bus (SMBus). The ISL88731 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 ISL88731 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 area. Low
offset current-sense amplifiers provide high accuracy with
10mΩ sense resistors. The ISL88731 provides 0.5
end-of-charge battery voltage accuracy.
The ISL88731 provides a digital output that indicates the
presence of the AC adapter as well as an analog output which
indicates the adapter current within 4 accuracy.
The ISL88731 is available in a small 5mmx5mm 28 Ld Thin
(0.8mm) QFN package. An evaluation kit is available to reduce
design time. The ISL88731 is available in Pb-Free packages.
