DESCRIPTION

The MP2615 is a high efficiency switch mode

battery charger suitable for 1- or 2- cell lithium-

ion

or

lithium-Polymer

applications.

The

MP2615 is capable of delivering 2A of charge

current programmable via an accurate sense

resistor over the entire input range.

The MP2615 regulates the charge current and

full battery voltage using two control loops to

achieve high accuracy constant current (CC)

charge and constant voltage (CV) charge.

Constant-off-time (COT) mode control allows

operation up to 99% duty cycle when the

battery voltage is close to the input voltage and

in order to keep charge current always at a

relative high level.

Battery temperature and charging status are

always monitored during each charging cycle.

Two status monitor output pins are provided to

indicate the battery charging status and input

power status. The MP2615 also features

internal reverse blocking protection.

The MP2615 is available in a 3mm × 3mm 16-

pin QFN package.
