Narrow VDC Regulator/Charger with SMBus Interface

The ISL9519 is a highly integrated Narrow VDC system voltage

regulator and battery charger controller. Operating parameters

are programmable over the System Management Bus (SMBus).

The ISL9519 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 ISL9519 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 ISL9519 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.

Features

• ±0.5% System Voltage Accuracy (-10°C to +100°C)

• ±3% Accurate Input Current Limit (-10°C to +100°C)

• ±3% Accurate Battery Charge Current Limit

• Variable Switching Frequency at Light Load Conditions for

Higher Efficiency

• Fixed Frequency Operation at Higher Loads

- Fixed Frequency Mode can be Forced by an External Pin

• Trickle Charge System for Deeply Discharged Batteries

- Automatic Trickle Charge Current (256mA)

- Holds Minimum Voltage to System

• SMBus 2-Wire Serial Interface

• Default System Voltage Values for 1-Cell, 2-Cell or

3-Cell Operation Selected by an External Pin

• Adapter In-rush FET Control

• Adapter Isolation FET Control

• Battery Short Circuit Protection

• Fast System-Load Transient Response

The ISL9519 provides an open drain digital output that

indicates the presence of the AC-adapter. The ISL9519 also

provides an analog output that indicates the adapter current.

• Monitor Outputs
