EUP8057

Advanced 1A Linear Charge

怎

Management Controllers

FEATURES

DESCRIPTION

4.5V-15V Wide Input Voltage Range

Ideal for Single Cell (4.1V or 4.2V) and Dual-Cell

(8.2V or 8.4V) Li-Ion or Li-Pol Batteries

Preset Charge Voltage with ±1% Accuracy

Programmable Charge Current up to 1A

Constant-Current/Constant Voltage Operation

Preconditioning of Low Voltage Cells

The EUP8057 is a highly advanced 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,

TSSOP-8 package.

The EUP8057 applies a constant current up to 1A to the

battery and the charge current can be programmed

externally with a sense-resistor.

The EUP8057 automatically terminates the charge cycle

when the charge current drops to the charge termination

threshold (I_TERM) after the charge-regulation voltage is

reached.

Optional Cell-Temperature Monitoring Before and

During Charge

Charge Status Output for Single of Dual Led or

Host Processor Interface

Automatic Battery Recharge

Charge Termination by Minimum Current

Automatic Low-Power Sleep Mode When Input

When the input supply is removed, the EUP8057

Power is Removed

automatically enters a low-power sleep mode.

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

Package

RoHS Compliant and 100% Lead (Pb)-Free

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.

APPLICATIONS

Cellular Phones / PDAs/ MP3 Players/DSC

Handheld Instruments
