DESCRIPTION

MP2607 is a highly-integrated single-cell Li-

Ion/Li-Polymer battery charger with system

power path management function. It takes input

from either AC adapter or USB port to supply

the

system

and

charge

the

battery

independently. The charger section features

trickle charge, high-accuracy constant current

(CC) and constant voltage (CV) regulation,

charge termination and charge status.

The system power path management function

ensures continuous supply to the system by

automatically selecting the input, the battery or

both to power the system. This section features

a low drop-out regulator from input to system,

and a 50mΩ switch from battery to system.

Power path management separates charging

current from system load, which allows proper

charge termination and keeps battery stay fully-

charged. It also allows instantaneous power up

of system with a deeply discharged battery.

MP2607 is available in 14pin 3mm*4mm QFN

package.
