ISL9518, ISL9518A

Data Sheet

December 8, 2008

FN6775.0

Narrow VDC Regulator/Charger with

SMBus Interface

Features

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

• ±3% Accurate Input Current Limit

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. High efficiency is

achieved with a DC/DC synchronous-rectifier buck converter,

equipped with diode emulation for enhanced light load

efficiency and AC-adapter boosting prevention. The ISL9518,

ISL9518A can charge two to four series connected

• ±3% Accurate Battery Charge Current Limit

• Switching Frequency can be Reduced via SMBus for

Higher Efficiency at Light Load Conditions

• Trickle Charge System for Deeply Discharged Batteries

- Automatic Trickle Charge Current (256mA)

- Holds Minimum Voltage to System

• SMBus 2-Wire Serial Interface

• Battery Short Circuit Protection

• Fast System-Load Transient Response

• Monitor Outputs

- Adapter Current (2.5% Accuracy)

- Trickle Charge Mode Indicator

- AC-Adapter Present Indicator

Lithium-ion cells, at up to 8A charge current. The ISL9518

has default settings for 2-cell systems and the ISL9518A has

default settings for 3-cell systems. Integrated MOSFET

drivers and bootstrap diode result in fewer components and

smaller implementation area. Low offset current-sense

amplifiers provide high accuracy.

• 11-Bit Max System Voltage Setting

• 7-Bit Min System Voltage Setting

• 6-Bit Charge Current Setting

The ISL9518, ISL9518A provide two open drain digital

outputs that indicate the presence of the AC adapter and

trickle charge state. Trickle charge state and AC adapter

present indicators are also available via SMBus. The

ISL9518, ISL9518A also provide two analog outputs that

indicate the adapter current and battery discharge current

with 4% accuracy.

• 6-Bit Adapter Current Setting

• Over 8A Battery Charger Current

• Over 8A Maximum Adapter Current

• +8V to +22V Adapter Voltage Range

• Pb-Free (RoHS Compliant)
