Product Details
The DS2780 remains in production, however, for new projects, we recommend ModelGauge m5 MAX17211 fuel gauge.
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.Applications
- 3G Multimedia Wireless Handsets
- Digital Still Cameras
- Handheld PC Data Terminals
- Subnotebook Computers
