MP2615B

2A, 1 Cell Li-ion Battery Charger

In 3mm x 3mm Package

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2615B is a monolithic switching charger

for a 1 cell lithium-Ion or lithium-Polymer battery

packed with built-in power MOSFETs. It’s able

to achieve up to 2A charge current which can

be programmed via an accurate sense resistor

over the whole input range.

•

4.5V to 18V Operating Input Voltage

Up to 99% Duty Cycle Operation

Up to 2A Programmable Charging Current

±0.75% Full Battery Voltage Accuracy

4.03V and 3.99V Selection for Full Battery

Voltage

•

Full Integrated Power Switches

Internal Loop Compensation

No External Reverse Blocking Diode

Required

MP2615B regulates the charge current and full

battery voltage using two control loops to

realize 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

Thanks to the constant-off-time (COT) mode

control, 99% duty cycle can be achieved when

battery voltage is close to the input voltage to

keep the charge current always at a relative

high level.

Battery temperature and charging status are

always monitored for each condition. Two

status monitor output pins are provided to

indicate the battery charging status and input

power status. The MP2615B 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 MP2615B is available in QFN-16

(3mmx3mm) package.
