DS2755

The DS2755 high-precision battery fuel gauge is a data-acquisition and information-storage device tailored for cost-sensitive and space-constrained 1-cell Li+/polymer battery-pack applications. The DS2755 provides the key hardware components required to accurately estimate remaining capacity by integrating low-power, precision measurements of
temperature, voltage, current, and current 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 DS2755 gives the host system read/write access to status and control registers, instrumentation registers, and generalpurpose 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.
