Product Description

Highly Integrated Narrow VDC Battery Charger for Notebook Computers
The ISL6257 is a highly integrated battery charger controller for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for Narrow VDC applications where the system power source is either the battery pack or the regulated output of the charger. This makes the max voltage to the system equal to the max battery voltage instead of the max adapter voltage. Operating at lower system voltage can improve overall efficiency. High efficiency is achieved in the charger with a synchronous buck topology. The low-side MOSFET emulates a diode at light loads to improve the light loadefficiency and prevent system bus boosting.
Features
• ±0.5% Charge Voltage Accuracy (-10°C to +100°C)
• ±3% Accurate Input Current Limit
• ±3% Accurate Battery Charge Current Limit
• ±25% Accurate Battery Trickle Charge Current Limit
• Programmable Charge Current Limit, Adapter Current Limit and Charge Voltage
• Fixed 300kHz PWM Synchronous Buck Controller with Diode Emulation at Light Load
• 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
• Aircraft Power Capable
• DC Adapter Present Indicator
• Battery Discharge MOSFET Control
• Less than 10µA Battery Leakage Current
• Support Pulse Charging
• Charge any Battery Chemistry: Li-Ion, NiCd, NiMH, etc.
• Pb-Free Plus Anneal Available (RoHS Compliant)
Applications
• Notebook, Desknote and Sub-notebook Computers
• Personal Digital Assistant
