GENERAL DESCRIPTION

FEATURES

The DS2780 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.

Precision Voltage, Temperature, and Current

Measurement System

Internal Time Base is Accurate and Temperature

Stable

Absolute and Relative Capacity Estimated from

Coulomb Count, Discharge Rate, Temperature

and Battery Cell Characteristics

Accurate Warning of Low Battery Conditions

Automatic Backup of Coulomb Count and Age

Estimation to Nonvolatile (NV) EEPROM

Gain and Tempco Calibration Allows the Use of

Low-Cost Sense Resistors

APPLICATIONS
