MP2623

Stand-Alone, 2A, 1- or2-Cell

Switching LiFePO₄Battery Charger

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2623 is a monolithic, DC-DC, step-

down, switching charger for a 1-or-2-cell serial

LiFePO₄battery. It has an integrated high-side

power MOSFET that can output up to a 2A

charge current. It also has peak-current–mode

control for fast loop response and easy

compensation.



Charges 1- and 2-Cell LiFePO₄Battery

Packs

Wide Operating-Input Range

Programmable Charging Current of up to 2A

±0.75% V_BATTAccuracy

0.2Ω Integrated Power MOSFET

Up to 90% Efficiency

Fixed 1.1MHz Frequency

Preconditioning for Fully-Depleted Batteries

Charging Status Indicator

Input Supply Fault Indicator

Thermal Shutdown

Cycle-by-Cycle Over-Current Protection

Battery Temperature Monitor and Protection



The MP2623 uses a sense resistor to control a

programmable charge current, and accurately

regulates the charge current and the charge

voltage using two control loops.

The MP2623 has multiple fault-condition

protections that include cycle-by-cycle current

limiting and thermal shutdown. Other safety

features include battery temperature monitoring

and protection, charge status indication and a

programmable timer to halt charging after a set

time period.

APPLICATIONS



Power Tools and Portable Equipment

Handheld Terminals

LiFePO₄Battery Chargers

The MP2623 requires a minimal number of

readily-available external components.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
