Narrow VDC Regulator/Charger with SMBus Interface and Internal Switching FETs ISL9519C The ISL9519C is a highly integrated Narrow VDC system voltage regulator and battery charger controller. Operating parameters are programmable over the System Management Bus (SMBus). The ISL9519C is 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 ISL9519C also includes a patented system to control trickle charging deeply discharged batteries while maintaining system voltage at a user defined minimum.
