MP2759

36V 3A Switching Charger with Integrated MOSFETs and Power Path Management for 1-6 Cell Batteries

Datasheet

概要

The MP2759 is a highly integrated switching charger designed for applications with 1-cell to 6-cell series Li-ion or Li-polymer battery packs. The device supports several battery chemistry types with different battery regulation voltages.

The device operates from a maximum 36V DC input voltage and hold-off up to 45V. 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 over-voltage protection, battery temperature sensing and protection, thermal shutdown, and a charging safety timer.

The MP2759 is available in a small QFN-19 (3mmx3mm) package.
