MP2615A

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

in 3mm x 3mm Package

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2615A is a high-efficiency, switch mode

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

ion or lithium-polymer applications. The

MP2615A is capable of delivering 2 A of charge

current programmable via an accurate sense

resistor over the entire input range.

•

4.75 V to 18 V Operating Input Voltage

Up to 99% Duty Cycle Operation

Up to 2 A Programmable Charging Current

±0.75% Full Battery Voltage Accuracy

4.2 V/Cell and 4.35 V/Cell Selection for Full

Battery Voltage

•

Fully Integrated Power Switches

Internal Loop Compensation

No External Reverse-Blocking Diode

Required

The MP2615A 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)

control

allows

operation at up to 99% duty cycle when the

battery voltage is close to the input voltage,

ensuring the charge current always remains at

a relatively high level.

The 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. Also, the MP2615A

features internal reverse-blocking protection.

APPLICATIONS

•

Smart Phones

Portable Hand-Held Solutions

Portable Media Players
