DESCRIPTION

The MP2604 is a linear, high-performance

single cell Li-Ion battery charger. By integrating

high voltage input protection into the charger IC,

the MP2604 can tolerate an input surge up to

28V.

The device features constant current (CC) and

constant voltage (CV) charging modes with

programmable charge currents (85mA to 1A),

programmable battery full threshold, thermal

protection, battery temperature monitoring and

reverse current blocking. The device also

provides AC adapter power good and charge

status indications to the system.

MP2604 is available in 10-pin 3mm x 3mm QFN

package.
