DS2782E+T&R Datasheet PDF - Maxim Integrated

The DS2782E+T&R from Maxim Integrated Products is a stand-alone fuel gauge IC in 8 pin TSSOP package. It 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. It is used in digital still cameras, sub-notebook computers, handheld PC data terminals and 3G multimedia wireless handsets.
