MP26123  
2A,24V Input, 600kHz  
2/3-Cell Switching Li-ion Battery Charger  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP26123 is a monolithic DC-DC step-  
down switching charger for 2- or 3-cell Li-ion  
battery packs. It has an integrated high-side  
power MOSFET can output up to a 2A charge  
current. It also has peak-current–mode control  
for fast loop response and easy compensation.  
Charges 2- or 3-Cell Li-Ion Battery Packs  
Wide Operating Input Range  
Programmable Charging Current of up to 2A  
±0.75% VBATT Accuracy  
0.2Integrated Power MOSFET  
Up to 90% Efficiency  
Fixed 600kHz Frequency  
Preconditioning for Fully Depleted Batteries  
Charging Status Indicator  
Input Supply Fault Indicator  
Thermal Shutdown  
Cycle-by-Cycle Over-Current Protection  
Battery Temperature Monitor and Protection  
The MP26123 uses a sense resistor to control a  
programmable charge current, and accurately  
regulates the charge current and charge  
voltage using two control loops.  
The MP26123 has multiple fault condition  
protections that include cycle-by-cycle current  
limiting and thermal shutdown. Other safety  
features include battery temperature monitoring  
and protection, charge status indication and  
programmable timer to cease the charging  
cycle when timer out.  
APPLICATIONS  
Mobile Internet Device  
Portable Media Player  
Netbook  
Charger for 2- or 3-Cell Li-Ion Batteries  
Distributed Power Systems  
The MP26123 requires a minimal number of  
readily-available external components.  
The MP26123 is available in a 4mm x 4mm 16-  
pin QFN package.
