EUP8051

Low Cost 1A Linear Battery Charge

Controllers

FEATURES

DESCRIPTION

Programmable Charge Current up to 1A

4.5V-7V Input Voltage Range

The EUP8051 is a single Lithium-Ion (Li-Ion) and

Lithium–Polymer (Li-Pol) linear charge management

controller for use in cost sensitive and portable

applications. It combines high accuracy constant-current

and constant-voltage regulation, cell preconditioning,

temperature monitoring, automatic charge termination,

charge-status indication, in a space-saving MSOP-8

package.

The EUP8051 applies a constant current up to 1A to the

battery and the charge current can be programmed

externally with a sense-resistor.

The EUP8051 automatically terminates the charge cycle

when the charge current drops to the charge termination

threshold (I_TERM) after the charge-regulation voltage is

reached.

When the input supply is removed, the EUP8051

automatically enters a low-power sleep mode, dropping

the battery drain current to less than 1µA.

A battery charge state output pin is provided to indicate

battery charge status through a display LED. The battery

charge status output is a serial interface which may also be

read by a system microcontroller.

Ideal for Single Cell (4.1V or 4.2V) Li-Ion or

Li-Pol Batteries

Preset Charge Voltage with ±1% Accuracy

Constant-Current/Constant Voltage Operation

Preconditioning of Low Voltage Cells

Optional Cell-Temperature Monitoring Before and

During Charge

Charge Status Indication

Automatic Battery Recharge

Charge Termination by Minimum Current

Automatic Low-Power Sleep Mode When Input

Power is Removed

Available in MSOP-8,TSSOP-8 and SOP-8

Package

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

Cellular Phones / PDAs/ MP3 Players/DSC

Handheld Instruments
