Product Overview
The DS2780E+ is a stand-alone fuel gauge IC in 8 pin TSSOP package. The device 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.
- Supply voltage range is 2.5V to 4.5V
- Operating temperature range from -40°C to 85°C
- Precision voltage, temperature and current measurement system
- Internal time base is accurate and temperature stable
- Accurate warning of low battery conditions
- Automatic backup of coulomb count and age estimation to non-volatile (NV) EEPROM
- Gain and tempco calibration allows the use of low-cost sense resistors
- 16byte user EEPROM, 24byte battery/application parameter EEPROM
- Unique ID and multidrop 1-wire interface
Applications
Power Management, Portable Devices, Wireless
