DESCRIPTION

The MP2759A 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 MP2759A

charges the battery with four phases: trickle

charge, pre-charge, constant current (CC)

charge, and constant voltage (CV) charge.

The MP2759A offers an input current limit

function 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 MP2759A

automatically reduces the charge current to limit

the input power.

To guarantee safe operation, the MP2759A

includes robust protection features such as

battery over-voltage protection (OVP), battery

temperature sensing and protection, thermal

shutdown, and a charging safety timer.

The MP2759A is available in a small QFN-19

(3mmx3mm) package.
