GENERAL DESCRIPTION

FEATURES

The DS2782 measures voltage, temperature and

current, and estimates available capacity for

rechargeable lithium ion and lithium-ion polymer

batteries. Cell characteristics and application

parameters used in the calculations are stored in on-

chip EEPROM. The available capacity registers

report a conservative estimate of the amount of

charge that can be removed given the current

temperature, discharge rate, stored charge and

application parameters. Capacity estimation reported

in mAh remaining and percentage of full.

Cꢀ Precision Voltage, Temperature, and Current

Measurement System

Cꢀ Accurate Stable Internal Time Base

Cꢀ Absolute and Relative Capacity Estimated from

Coulomb Count, Discharge Rate, Temperature

and Battery Cell Characteristics

Cꢀ Accurate Warning of Low Battery Conditions

Cꢀ Automatic Backup of Coulomb Count and Age

Estimation to Nonvolatile (NV) EEPROM

Cꢀ Gain and Tempco Calibration Allows the Use of

Low-Cost Sense Resistors

APPLICATIONS

Cꢀ 24-Byte User EEPROM or 16-Byte User

EEPROM and Unique 64-bit ID

Digital Still Cameras

Cꢀ Industry 2-Wire Interface with Programmable

Slave Address

Cꢀ Tiny 8-Pin TSSOP Package Embeds Easily in

Battery Packs Using Thin Prismatic Cells
