MP2619

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 MP2619 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

0.2Ω 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



MP2619 regulates the battery 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 to

power the system. Power path management

separates charging current from system load.

When the MP2619 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 finish the charging cycle.



Pre-Regulator for Linear Regulators

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.
