MP2759GQ集成电路（IC）的电池充电器规格书PDF中文资料

DESCRIPTION

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.
