MP2615

2A, 1- or 2- Cell Li-ion Battery Charger

In 3mm x 3mm Package

DESCRIPTION

FEATURES

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.



4.75V to 18V Operating Input Voltage

Up to 99% Duty Cycle Operation

Up to 2A Programmable Charging Current

±0.75% Full Battery Voltage Accuracy

4.1V/Cell and 4.2V/Cell Selection for Full

Battery Voltage



Full Integrated Power Switches

Internal Loop Compensation

No External Reverse Blocking Diode

Required

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.



Preconditioning for Fully Depleted Battery

Charging Operation Indicator

Programmable Safety Timer

Thermal Shutdown Protection

Cycle-by-Cycle Over Current Protection

Battery Temperature Monitor and Protection

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.

APPLICATIONS



Smart Phones

Portable Hand-held Solutions

Portable Media Players

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.

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

pin QFN package.
