MP2612  
2A,24V Input, 600kHz  
2/3-Cell Switching Li-Ion Battery Charger  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
Charges 2-3 Cells Li-Ion Battery Packs  
Wide Operating Input Range  
Up to 2 A Programmable Charging Current  
±0.75% VBATT Accuracy  
0.2Internal 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  
Battery Temperature Monitor and Protection  
The MP2612 is a monolithic switching charger  
for 2 or 3 cells 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.  
MP2612 regulates the charge current and  
charge voltage using two control loops to  
realize high accuracy CC charge and CV  
charge.  
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.  
APPLICATIONS  
Distributed Power Systems  
Chargers for 2-Cell or 3-Cell Li-Ion Batteries  
Pre-Regulator for Linear Regulators  
Smart Phones  
The MP2612 requires a minimum number of  
readily available standard external components.  
Net-book  
The MP2612 is available in 16-pin 4mm×4mm  
QFN package.
