MP2615A  
2 A, 1- or 2- Cell Li-Ion Battery Charger  
in 3mm x 3mm Package  
MPS CONFIDENTIAL AND PROPRIETARY INFORMATION– INTERNAL USE ONLY  
DESCRIPTION  
FEATURES  
The MP2615A is a high-efficiency, switch mode  
battery charger suitable for 1- or 2- cell lithium-  
ion or lithium-polymer applications. The  
MP2615A is capable of delivering 2 A of charge  
current programmable via an accurate sense  
resistor over the entire input range.  
4.75 V to 18 V Operating Input Voltage  
Up to 99% Duty Cycle Operation  
Up to 2 A Programmable Charging Current  
±0.75% Full Battery Voltage Accuracy  
4.2 V/Cell and 4.35 V/Cell Selection for Full  
Battery Voltage  
Fully Integrated Power Switches  
Internal Loop Compensation  
No External Reverse-Blocking Diode  
Required  
The MP2615A regulates the charge current and  
full battery voltage using two control loops to  
achieve high-accuracy constant current (CC)  
charge and constant voltage (CV) charge.  
Preconditioning for Fully Depleted Battery  
Charging Operation Indicator  
Programmable Safety Timer  
Thermal Shutdown Protection  
Cycle-by-Cycle Over-Current Protection  
Battery Temperature Monitor and Protection  
Constant-off-time  
(COT)  
control  
allows  
operation at up to 99% duty cycle when the  
battery voltage is close to the input voltage,  
ensuring the charge current always remains at  
a relatively high level.  
The battery temperature and charging status  
are always monitored during each charging  
cycle. Two status monitor output pins are  
provided to indicate the battery charging status  
and input power status. Also, the MP2615A  
features internal reverse-blocking protection.  
APPLICATIONS  
Smart Phones
