MP2661
4.65V System, 500mA, I2C-Controlled Battery Charger with Power Path
Management for Single-Cell Li-Ion Battery
DESCRIPTION
The MP2661 is a highly integrated, single-cell, lithium-ion (Li-ion) and lithium-polymer (Li-polymer) battery charger with system power path management for space-limited, portable applications. The MP2661 uses input power from either an AC adapter or a USB port to supply the system load and charge the battery independently. The charger features constant current pre-charge (PRE.C), constant current (CC) fast charge, and constant voltage (CV) regulation, charge termination, and autorecharge.
The power path management function ensures continuous power to the system by automatically selecting the input, the battery, or both to power the system.
