MP2635  
2A Single Cell Switch Mode Battery Charger  
with Power Path Management and Boost OTG  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2635 is a highly-integrated, flexible,  
switch-mode battery charge management and  
system power path management device for a  
single-cell Li-ion and Li-Polymer battery used in  
a wide range of portable applications.  
4.5V-to-6V Operating Input Voltage Range  
Power Management Function Integrated  
Input-Current Limit and Input-Voltage  
Regulation  
Up to 2A Programmable Charge Current  
Trickle-Charge Function  
The MP2635 has two operating modes—charge  
mode and boost mode—to allow management  
of system and battery power based on the state  
of the input.  
Selectable 3.6V/ 4.2V Charge Voltage with  
0.5% Accuracy  
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 System  
Power  
Up to 91% 5V Boost Mode Efficiency @ 1A  
Programmable Output Current Limit for  
Boost Mode  
When input power is present, the device  
operates in charge mode. It automatically  
detects the battery voltage and charges the  
battery in the three phases: trickle current,  
constant current and constant voltage. Other  
features include charge termination and auto-  
recharge. This device also integrates both input  
current limit and input voltage regulation in  
order to manage input power and meet the  
priority of the system power demand.  
Integrated Short Circuit Protection for Boost  
Mode  
In the absence of an input source, the MP2635  
switches to boost mode through the MODE pin  
to power the SYS pins from the battery. The  
OLIM pin programs the output current limit in  
boost mode. The MP2635 also allows an output  
short-circuit thanks to an output disconnect  
feature, and can auto-recover when the short  
circuit fault is removed.  
APPLICATIONS  
Sub-Battery Applications  
Power-Bank Applications for Smart-Phone  
Tablet and Other Portable Devices  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Products, Quality Assurance page.

Monolithic Power Systems, Inc.  
The MP2635 provides full operating status  
indication to distinguish charge mode from  
boost mode.  
The  
MP2635  
achieves  
low  
EMI/EMC  
performance with well-controlled switching  
edges.  
To guarantee safe operation, the MP2635 limits  
the die temperature to a preset value 120oC.  
Other safety features include input over-voltage  
protection, battery over-voltage protection,  
thermal  
shutdown,  
battery  
temperature  
monitoring, and a programmable timer to  
prevent prolonged charging of a dead battery.
