MP2639A

2-Cell Li-Ion or Li-Polymer Switching Charger

Compatible with 5V Input and

Integrated, Bidirectional Charge/Discharge

DESCRIPTION

FEATURES

The MP2639A is a highly integrated, flexible,

switch-mode, battery-charging management

device for 2-cell series Li-ion and Li-polymer

batteries used in a wide range of portable

applications.



4.0V to 5.75V Input Voltage Range

Charge 2-Cell Batteries with 5V Input

USB-Compliant Charger

Integrates Input Current-Based and Input

Voltage-Based Power Management

Functions

Programmable Input Current and Input

Voltage Limit

Up to 2.5A Programmable Charge Current

for 2-Cell Applications

8.4V Charge Voltage with 0.5% Accuracy

Up to 5.0A Programmable Discharge

Current

Negative Temperature Coefficient Pin for

Temperature Monitoring

The MP2639A is able to charge a 2-cell battery

from a 5V adapter or USB input. The MP2639A

can work in three modes: charge mode,

discharge mode, and sleep mode.



In 2-cell applications, the 5V input charges the

2-cell battery via the MP2639A operating in

step-up mode. When the 5V input is absent, the

2-cell battery voltage is discharged to the 5V

output via the MP2639A working in step-down

mode.



No Load Shutdown and Push Button Turn-

On in Discharge Mode

For the charging function, the MP2639A detects

the battery voltage automatically and charges

the battery in three phases: trickle current,

constant current, and constant voltage. Other

features include charge termination and auto-

recharge.



Programmable Timer Back-Up Protection

Discharge Mode Load Trace Compensation

Thermal Regulation and Thermal Shutdown

Internal Battery Reverse Leakage Blocking

Integrated Short-Circuit Protection (SCP) for

Both Charge and Discharge Mode

Four LED Battery Level and Status

Indicators

To guarantee safe operation, the MP2639A

limits the die temperature to a preset value of

120°C. Other safety features include input over-

voltage protection (OVP), battery over-voltage

protection (OVP), thermal shutdown, battery

temperature monitoring, and a programmable

timer to prevent prolonged charging of a dead

battery.



Available in a QFN-26 (4mmx4mm)

Package

APPLICATIONS



Power Station Applications

Power Bank Applications for Smart Phones,

Tablets, and Other Portable Devices

Mobile Internet Devices

The MP2639A is available in a QFN-26

(4mmx4mm) package.
