ISL88731C规格书详情
The 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 area. 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 which
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.
