ISL6256, ISL6256A

Highly Integrated Battery Charger with Automatic Power Source Selector for

Notebook Computers

FN6499

Rev 3.00

September 14, 2010

The ISL6256, ISL6256A is a highly integrated battery charger

controller for Li-ion/Li-ion polymer batteries. High Efficiency is

Features

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

• ±3% Accurate Input Current Limit

achieved by a synchronous buck topology and the use of a

MOSFET, instead of a diode, for selecting power from the

adapter or battery. The low side MOSFET emulates a diode at

light loads to improve the light load efficiency and prevent

system bus boosting.

• ±3% Accurate Battery Charge Current Limit

• ±25% Accurate Battery Trickle Charge Current Limit

• Programmable Charge Current Limit, Adapter Current

Limit and Charge Voltage

The constant output voltage can be selected for 2, 3 and 4

series Li-ion cells with 0.5% accuracy over-temperature. It can

also be programmed between 4.2V + 5%/cell and

• Fixed 300kHz PWM Synchronous Buck Controller with

Diode Emulation at Light Load

4.2V - 5%/cell to optimize battery capacity. When supplying

the load and battery charger simultaneously, the input current

limit for the AC adapter is programmable to within 3%

accuracy to avoid overloading the AC adapter, and to allow

the system to make efficient use of available adapter power

for charging. It also has a wide range of programmable

charging current. The ISL6256, ISL6256A provides outputs

that are used to monitor the current drawn from the AC

adapter, and monitor for the presence of an AC adapter. The

ISL6256, ISL6256A automatically transitions from regulating

current mode to regulating voltage mode.

• Overvoltage Protection

• Output for Current Drawn from AC Adapter

• AC Adapter Present Indicator

• Fast Input Current Limit Response

• Input Voltage Range 7V to 25V

• Support 2-, 3- and 4-Cells Battery Pack

• Up to 17.64V Battery-Voltage Set Point

• Control Adapter Power Source Select MOSFET

• Thermal Shutdown

ISL6256, ISL6256A has a feature for automatic power source

selection by switching to the battery when the AC adapter is

removed or switching to the AC adapter when the AC adapter is

available. It also provides a DC adapter monitor to support

aircraft power applications with the option of no battery charging.

• Aircraft Power Capable

• DC Adapter Present Indicator

• Battery Discharge MOSFET Control

• Less than 10µA Battery Leakage Current

• Supports Pulse Charging

NOTES:

1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on

reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is

RoHS compliant and compatible with both SnPb and Pb-free

soldering operations). Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.

3. For Moisture Sensitivity Level (MSL), please see device information

page for ISL6256, ISL6256A. For more information on MSL please

see techbrief TB363.
