MP2626  
USB-Compliant Single Cell Li-ion  
Switching Charger with USB-OTG Boost  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2626 is a highly-integrated, flexible,  
switch-mode battery charger with system power  
management, designed for single-cell Li-ion  
and Li-Polymer batteries used in a wide range  
of portable applications.  
20V Absolute Maximum Input Voltage  
6V Maximum Input Operating Voltage  
Selectable 4.2V/ 4.35V Charge Voltage with  
0.5% Accuracy at 25ºC  
Power Management Function  
Integrated Input-Current Limit and Input-  
Voltage Regulation  
Up to 2A Programmable Charge Current  
Trickle-Charge Function  
The MP2626 can operate in both charge mode  
and boost mode to allow full system and battery  
power management. It is also able to work as a  
boost regulator to power a USB peripheral from  
the battery.  
Negative Temperature Coefficient Pin for  
Battery Temperature Monitoring  
Programmable Timer Back-Up Protection  
Thermal Regulation and Thermal Shutdown  
Internal Battery Reverse Leakage Blocking  
Reverse Boost Operation Mode for USB  
Peripheral  
Up to 91% 5V Boost Mode Efficiency @ 1A  
Programmable Output Current Limit for  
Boost Mode  
The MP2626 automatically detects the battery  
voltage and charges the battery in the three  
phases: trickle current charge, constant current  
charge and constant voltage charge. Other  
features include charge termination and auto-  
recharge. This IC also integrates both input-  
current limit and input-voltage regulation in  
order to ensure USB compliant and minimize  
the charging time.  
Integrated Short Circuit Protection for Boost  
Mode  
The MP2626 can operate as a boost regulator  
by setting the MODE pin to a HIGH logic. The  
boost regulator includes output current limit and  
short circuit protection. As long as MODE pin is  
high, the MP2626 will discharge the battery in  
the boost mode.  
APPLICATIONS  
Sub-Battery Application  
Power-Bank Applications for Smart-Phone  
Tablet and other Portable Device  
To guarantee safe operation, the MP2626 limits  
the die temperature to a preset value of 120oC.  
Other safety features include input over-voltage  
protection, battery over-voltage protection,
