EUP8054/8054X

Standalone Linear Li-Ion Battery Charger

With Thermal Regulation in ThinSOT

FEATURES

DESCRIPTION

The EUP8054 is a complete constant-current/constant-

voltage linear charger for single cell lithium-ion batteries.

Its ThinSOT package and low external component count

make the EUP8054 ideally suited for portable applications.

Furthermore, the EUP8054 is specifically designed to

work within USB power specifications.

Programmable Charge Current Up to 800mA

No MOSFET, Sense Resistor or Blocking Diode

Required

Complete Linear Charger in ThinSOT Package for

Single Cell Lithium-ion Batteries

Constant-Current/Constant-Voltage Operation with

Thermal Regulation to Maximize Charge Rate

Without Risk of Overheating

No external sense resistor is needed, and no blocking

diode is required due to the internal MOSFET architecture.

Thermal feedback regulates the charge current to limit the

die temperature during high power operation or high

ambient temperature. The charge voltage is fixed at 4.2V,

and the charge current can be programmed externally with

a single resistor. The EUP8054 automatically terminates

the charge cycle when the charge current drops to 1/10th

the programmed value after the final float voltage is

reached.

Charges Single Cell Li-Ion Batteries Directly from

USB Port

Preset 4.2V Charge Voltage with ± 1% Accuracy

Charge Current Monitor Output for Gas Gauging

Automatic Recharge

Charge Status Output Pin

C/10 Charge Termination

25µA Supply Current in Shutdown

2.9V Trickle Charge Threshold (EUP8054)

Available Without Trickle Charge (EUP8054X)

Soft-Start Limits Inrush Current

When the input supply (wall adapter or USB supply) is

removed, the EUP8054 automatically enters a low current

state, dropping the battery drain current to less than 2µA.

The EUP8054 can be put into shutdown mode, reducing

the supply current to 25µA.

Other features include charge current monitor,

undervoltage lockout, automatic recharge and a status pin

to indicate charge termination and the presence of an input

voltage.

Available in TSOT-25, TDFN-6(3mm*3mm)

Package

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

Cellular Telephones/ PDAs/ MP3 Players

Charging Docks and CradIes

Bluetooth Applications
