MP2608

28V, 1A Dual Input

Linear Battery Charger With Timer

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2608 is

dual-input, linear,

•

Complete Solution for Charging Single-Cell

Lion-Ion Battery

Input Surge Up to 28V

high-performance low-cost single cell Li-Ion or

Li-Polymer battery charger. It accepts two

power inputs, one from a USB (Universal BUS)

port and the other from an AC adapter. By

integrating high voltage input protection into the

charger IC, the MP2608 can tolerate an input

surge up to 28V. Due to the protection inputs

function, low-cost, large output tolerance

adapters can be used safely.

•

Adapter and USB Input

Programmable Charge Current: 100mA to 1.0A

Pre-set USB Charge Current: 450mA

Proprietary Constant Voltage Auto Recharge

Proprietary Over-Voltage Protection

0.75% V_BATTAccuracy over Temperature

<1µA Battery Reverse Current

125µA Standby Current from V_IN

Battery Temperature Monitoring

Thermal Protection

The device features constant current (CC) and

constant voltage (CV) charging modes with

programmable charge currents (100mA to

1.0A), current blocking and trickle charge. The

charge current for adapter input can be

programmed by an external resistor, while the

charge current for USB input is pre-set at

450mA.The device also provides charge status

and fault indications to the system.

APPLICATIONS

•

Cell Phones

Digital Cameras

Smart Phones

PDAs

For guaranteed safe operation, the MP2608

folds back charge current when the device is

heated up due to limited PCB space. Other

safety

features

are

including
