DS2777G+

The DS2777G+ is a dual cell, stand-alone Li+ fuel gauge IC with protector in 14 pin TDFN package. This device supports rechargeable lithium-ion (Li+) and Li+ polymer (Li-Poly) batteries in mAh and as a percentage of full. Safe operation is ensured by the integrated Li+ protector. DS2777 capability includes precision measurements of voltage, temperature and current along with a cell characteristics table and application parameters. The 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. the device offers a 16 bytes of EEPROM for use by the host system and/or pack manufacturer to store battery lot and date tracking information. The EEPROM can also be used for non-volatile storage of system and/or battery usage statistics.
