GENERAL DESCRIPTION
The DS2756 high-precision battery fuel gauge is a
data-acquisition
and
information-storage
tailored for cost-sensitive and space-constrained 1-
cell Li+/polymer battery-pack applications. The
DS2756 provides the key hardware components
required to accurately estimate remaining capacity by
integrating low-power, precision measurements of
temperature,
voltage,
accumulation, as well as nonvolatile (NV) data
storage, into the small footprint of a 3.0mm x 4.4mm
8-pin TSSOP package.
Through its 1-Wire interface, the DS2756 gives the
host system read/write access to status and control
registers, instrumentation registers, and general-
purpose data storage. Each device has a unique
factory-programmed 64-bit net address that allows it
to be individually addressed by the host system,
supporting multibattery operation.
