Description

The ISL9519R is a highly integrated Narrow VDC system voltage regulator and battery charger controller. Operating

parameters are programmable over the System Management Bus (SMBus). The ISL9519R 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 ISL9519R also includes

a patented system to control trickle charging deeply discharged batteries while maintaining system voltage at a user

defined minimum. High efficiency is achieved with a DC/DC synchronous-rectifier buck converter, equipped with diode

emulation and variable switching frequency for enhanced light load efficiency and AC-adapter boosting prevention. The

ISL9519R can charge one, two or three series connected Lithium-ion cells, at up to 8A charge current. Default settings

for 1-, 2- or 3-cell operation at power-up are selected by an external pin. Integrated MOSFET drivers and bootstrap

diode result in fewer components and smaller implementation area. Low offset current-sense amplifiers provide high

accuracy.

The ISL9519R provides an open drain digital output that indicates the presence of the AC-adapter. The ISL9519R also

provides an analog output that indicates the adapter current.
