Overview
ICM SDA SCL VDDSM B GND ACOK NC ISL88731A SMBus Level 2 Battery Charger The ISL88731A is a highly integrated Lithium-ion battery charger controller, programmable over the SMBus system management bus (SMBus).
The ISL88731A 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 ISL88731A 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 sense resistors.
The ISL88731A provides 0.
5% end-of-charge battery voltage accuracy.
The ISL88731A provides a digital output that i...
