MP2759 is a highly integrated switching charger designed for applications with 1-cell to 6-cell series Li-ion or Li-polymer battery packs. When an input power supply is present, the MP2759 charges the battery with four phases: trickle charge, pre-charge, constant current (CC) charge and constant voltage (CV) charge. The MP2759 offers input current limiting and a minimum input voltage limit function. If the input current reaches the input current limit or the input voltage drops to the minimum input voltage limit, the MP2759 automatically reduces the charge current to limit the input power. To guarantee safe operation, the MP2759 includes robust protection features such as battery overvoltage protection, battery temperature sensing and protection, thermal shutdown and a charging safety timer. The MP2759 is available in a small QFN-19 (3mmx3mm) package. Applications include industrial medical equipment, power tools, wireless speakers, robot and portable vacuum cleaners.
