MP2659 36V, Standalone Switching Charger with Integrated MOSFETs for 3-Cell to 6-Cell Series Battery Pack DESCRIPTION The MP2659 is a highly integrated switching charger designed for portable devices with 3-cell to 6-cell series Li-ion or Li-polymer battery packs. The device achieves up to 3A of charge current with different battery regulation voltages. The device operates under a maximum 36V DC input voltage and hold-off up to 45V. When an input power supply is present, the MP2659 charges the battery with three phases: precharge, constant current charge, and constant voltage charge. Power management is based on the input current and input voltage.
