GENERAL DESCRIPTION
The DS2782 measures voltage, temperature and
current, and estimates available capacity for
rechargeable lithium ion and lithium-ion polymer
batteries.
Cell
characteristics
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.
APPLICATIONS
