MP2672 - Boost Charger

Description

The MP2672 is a 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.

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. It monitors the voltage across each cell and equalizes cell voltages once the difference exceeds the mismatch threshold. The MP2672 has two configuration modes: sta.

MP2672 Boost Charger with Cell Balance for 2-Cell Series Lithium-Ion Battery DESCRIPTION The MP2672 is a 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.
