MP2607DL-LF-P

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 50mO 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.
