Description
The MP2623 is a monolithic, DC-DC, step-down, switching charger for a 1-or-2-cell serial LiFePO4 battery. It has an integrated high-side power MOSFET that can output up to a 2A charge current. It also has peak-current–mode control for fast loop response and easy compensation. The MP2623 uses a sense resistor to control a programmable charge current, and accurately regulates the charge current and the charge voltage using two control loops. The MP2623 has multiple fault-condition protections that include cycle-by-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring and protection, charge status indication and a programmable timer to halt charging after a set time period. The MP2623 requires a minimal number of readily-available external components. The MP2623 is available in a 4mm×4mm 16-pin QFN package.
