Features: MP2639C 2-Cell Li-Ion or Li-Polymer Swit ching Charger Compatible with 5V Input and Integrated, Bidirectional Charge/Di scharge with Cell Balance DESCRIPTION The MP2639C is a highly integrated, fle xible, switch-mode, battery-charging ma nagement device for 2-cell series Li-io n and Li-polymer batteries used in a wi de range of portable applications. The MP2639C is able to charge a 2-cell batt ery from a 5V adapter or USB input. The MP2639C can work in three modes: charg e mode, discharge mode, and sleep mode. In 2-cell applications, the 5V input c harges the 2-cell battery via the MP263 9C operating in step-up mode. When the 5V input is absent, the 2-cell battery voltage is discharged to the 5V output via the MP2639C working in step-down mo de. For the charging function, the MP26 39C detects the battery voltage automat ically and charges the battery in three phases: trickle current, constant curr ent, and constant voltage. Other featur es include charge termination and autorecharge. To guarantee sa.

MP2639C
2-Cell Li-Ion or Li-Polymer Switching Charger
Compatible with 5V Input and Integrated,
Bidirectional Charge/Discharge with Cell Balance
DESCRIPTION
The MP2639C 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.
The MP2639C is able to charge a 2-cell battery
from a 5V adapter or USB input. The MP2639C
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 MP2639C operating in
step-up mode. When the 5V input is absent, the
2-cell battery voltage is discharged to the 5V
output via the MP2639C working in step-down
mode.
For the charging function, the MP2639C 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.
To guarantee safe operation, the MP2639C
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.
The MP2639C is available in a QFN-26
(4mmx4mm) package.
