MP2618  
2A, 24V Input, 600kHz  
2-3 Cell Switching Li-Ion Battery Charger  
With System Power Path Management  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2618 is a monolithic switching charger  
for 2-3 cell Li-Ion battery packs with a built-in  
internal power MOSFET. It achieves up to 2A  
charge current with current mode control for  
fast loop response and easy compensation.  
The charge current can be programmed by  
sensing the current through an accurate sense  
resistor.

±0.75% VBATT Accuracy  
0.28Ω Internal Power MOSFET Switch  
Up to 90% Efficiency  
Fixed 600kHz Frequency  
Preconditioning for fully depleted batteries  
Charging Operation Indicator  
Input Supply and battery fault indicator  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection

•
MP2618 regulates the charge voltage and  
charge current using two control loops to realize  
high accuracy CC charge and CV charge.  
The system power path management function  
ensures continuous supply to the system by  
automatically selecting the input or the battery.  
Power path management separates charging  
current from system load. When the MP2618  
realizes current sharing of the input current,  
charge current will drop down according to the  
increase of the system current.  
APPLICATIONS  
•
•
•
Netbook PC  
Distributed Power Systems  
Chargers for 2-Cell or 3-Cell Li-Ion  
Batteries  
Fault condition protection includes cycle-by-cycle  
current limiting, and thermal shutdown. Other  
safety features include battery temperature  
monitoring, charge status indication and  
programmable timer to cease the charging cycle.
