MP2658 36V, Standalone Switching Charger with Integrated MOSFETs for Multi-Cell Series Battery Pack DESCRIPTION The MP2658 is a highly integrated switching charger designed for portable devices with different battery chemistries. The MP2658 supports up to 7-cell series Li-ion, Li-polymer, and LiFePO4 battery packs. It also supports leadacid, super capacitor, NiMH, and NiCd battery packs from 2V to 31V. The device achieves up to 3A of charge current (ICC) with any battery regulation voltage (VBATT_REG). The device operates under a maximum 36V DC input voltage and hold-off voltage up to 45V. When an input power supply is present, the MP2658 charges the battery with four phases: trickle charge, pre-charge, constant current (CC) charge, and constant voltage (CV) charge.
