DESCRIPTION

The MP2605 is a linear, high-performance

single cell Li-Ion/Li-Polymer battery charger. By

integrating high voltage input protection into the

charger IC, the MP2605 can tolerate an input

surge up to +28V.

The device features constant current (CC) and

constant voltage (CV) charging modes with

programmable charge currents (200mA to 1A),

current blocking, and trickle charge. The device

also

provides

fault

and

charge

status

indications to the system.

For guaranteed safe operation, the MP2605

reduces charge current when the device

reaches high temperature (due to limited PCB

space). Other safety features include battery

temperature monitoring and programmable

timer to complete the charging cycle.

The MP2605 is available in 10-pin 3mm x 3mm

QFN packages.
