- Part Models
- 4
- 1ku List Price
- Starting From $4.56
Overview
- Precision Voltage, Temperature, and Current Measurement System
- Accurate Stable Internal Time Base
- 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
- 24-Byte User EEPROM or 16-Byte User EEPROM and Unique 64-Bit ID
- Industry 2-Wire Interface with Programmable Slave Address
- Tiny 8-Pin TSSOP and 10-TDFN Packages Embed Easily in Thin Prismatic Cell Packs
The DS2782 remains in production, however, for new projects, we recommend ModelGauge m5 MAX17201 fuel gauge.
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.Applications
- 3G Multimedia Wireless Handsets
- Digital Still Cameras
- Handheld PC Data Terminals
- Subnotebook Computers
