® ISL9518, ISL9518A Data Sheet December 8, 2008 FN6775.0 www.DataSheet4U.com Narrow VDC Regulator/Charger with SMBus Interface The ISL9518, ISL9518A are highly integrated Narrow VDC system voltage regulators and battery charger controllers. Operating parameters are programmable over the System Management Bus (SMBus). The ISL9518, ISL9518A are designed for applications where the system power source is either the battery pack or the output of the regulator/charger. This makes the max voltage to the system equal to the max battery voltage instead of the max adapter voltage. The ISL9518, ISL9518A also include a system to control trickle charging deeply discharged batteries while maintaining system voltage at a user defined minimum.
