MP2672GD-0000-P

Highly integrated, flexible switch-mode battery charger IC for a lithium-ion battery with two cells in series which is used in a wide range of portable applications. When the input power supply is present, the MP2672 operates in boost mode to charge the battery with two cells in series. When charging is enabled, the MP2672 automatically detects the battery voltage and charges the battery in three phases (pre-charge, constant-current charge, and constant-voltage charge). Other features include charge termination and auto-recharge. The MP2672 also has a narrow voltage DC (NVDC) power structure. When the battery is weak, the MP2672 regulates the system output at the minimum voltage level to power the system instantly and charge the battery via the battery FET simultaneously. The MP2672 also has cell balance function. Typical applications include portable handheld solutions, POS machines, Bluetooth speakers, E-cigarettes and general 2-cell applications.
