ISL88731
SMBus Level 2 Battery Charger
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 10m
Ω
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 5mm x 5mm 28 Ld thin
(0.8mm) QFN package. An evaluation kit is available to
reduce design time. The ISL88731 is available in Pb-free
packages.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb
and Pb-free soldering operations. Intersil Pb-free products are MSL classified
at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
