DESCRIPTION
The DS2434 Battery Identification Chip provides a convenient method of tagging and identifying battery
packs by manufacturer, chemistry, or other identifying parameters. The DS2434 allows the battery pack
to be coded with a unique identification number, and also store information regarding the battery life and
charge/discharge characteristics in its nonvolatile memory.
The DS2434 also performs the essential function of monitoring battery temperature, without the need for
a thermistor in the battery pack.
Information is sent to/from the DS2434 over a 1-Wire interface, so that battery packs need only have
three output connectors; power, ground, and the 1-Wire interface.
