MP2618

2A, 24V Input, 600kHz

2-3 Cell Switching Li-Ion Battery Charger

With System Power Path Management

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2618 is a monolithic switching charger

for 2-3 cell Li-Ion battery packs with a built-in

internal power MOSFET. It achieves up to 2A

charge current with current mode control for

fast loop response and easy compensation.

The charge current can be programmed by

sensing the current through an accurate sense

resistor.

•

Charges 2-3 cell Li-Ion battery packs

Wide Operating Input Range

Up to 2A Programmable Charging Current

Power Path Management with Current

Sharing

±0.75% V_BATTAccuracy

0.28Ω Internal Power MOSFET Switch

Up to 90% Efficiency

Fixed 600kHz Frequency

Preconditioning for fully depleted batteries

Charging Operation Indicator

Input Supply and battery fault indicator

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Battery Temperature Monitor and Protection

•

MP2618 regulates the charge voltage and

charge current using two control loops to realize

high accuracy CC charge and CV charge.

The system power path management function

ensures continuous supply to the system by

automatically selecting the input or the battery.

Power path management separates charging

current from system load. When the MP2618

realizes current sharing of the input current,

charge current will drop down according to the

increase of the system current.

APPLICATIONS

•

Netbook PC

Distributed Power Systems

Chargers for 2-Cell or 3-Cell Li-Ion

Batteries

Fault condition protection includes cycle-by-cycle

current limiting, and thermal shutdown. Other

safety features include battery temperature

monitoring, charge status indication and

programmable timer to cease the charging cycle.
