ISL88731 General Description

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 thecurrent from the AC adapter isautomatically 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.Features• 0.5% Battery Voltage Accuracy• 3% Adapter Current Limit Accuracy• 3% Charge Current Accuracy• SMBus 2 Wire Serial Interface• Battery Short Circuit Protection• Fast Response for Pulse-Charging• Fast System-Load Transient Response• Monitor Outputs- Adapter Current (3% Accuracy)- AC Adapter Detection• 11 Bit Battery Voltage Setting• 6 Bit Charge Current/Adapter Current Setting• 8A Maximum Battery Charger Current• 11A Maximum Adapter Current• +8V to +28V Adapter Voltage Range• Pb-Free Plus Anneal Available (RoHS Compliant)Applications• Notebook Computers• Tablet PCs• Portable Equipment with Rechargeable Batteries
