DS2788 Datasheet | Maxim Integrated

19-4639; Rev 2; 5/09 Stand-Alone Fuel-Gauge IC with LED Display Drivers General Description The DS2788 measures voltage, temperature, and current, and estimates available capacity for rechargeable lithium-ion (Li+) and Li+ 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 is reported in mAh remaining and percentage of full. LED display drivers and a debounced input make display of the capacity...
