DS2781G+

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.

• Supply voltage range is 2.5V to 10V
• Operating temperature range from -40°C to 85°C
• Accurate temperature stable internal timebase
• Accurate warning of low battery conditions
• Automatic backup of coulomb count and age estimation to non-volatile (NV) EEPROM
• Gain and temperature coefficient calibration allows the use of low-cost sense resistors
• 24byte parameter EEPROM
• 16byte user EEPROM
• Unique ID and multidrop 1-wire interface
