DS2781G+ Datasheet PDF - Maxim Integrated

The DS2781G+ is a 1-cell or 2-cell stand-alone fuel gauge IC in 10 pin TDFN package. This device measures voltage, temperature and current and estimates available capacity for rechargeable lithium-ion and lithium-ion polymer batteries. Cell stack characteristics and application parameters used in the calculations are stored in on-chip EEPROM. The capacity registers report a conservative estimate of the amount of charge from all application parameters. Capacity estimation is reported in milliamp hours remaining and percentage of full.
