DESCRIPTIONThe 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 packto 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.

DETAILED PIN DESCRIPTION
OVERVIEWThe DS2434 has five major components: 1) Scratchpad Memory, 2) Nonvolatile Memory, 3) On-board
SRAM, 4) Temperature Sensor, and 5) ID Register. All data is read and written least significant bit first.
Access to the DS2434 is over a 1-Wire interface. Charging parameters and other data such as battery
chemistry, gas gauge information, and other user data would be stored in the DS2434, allowing this
information to be permanently stored in the battery pack. Nonvolatile (E2) RAM holds information even
if the battery goes dead; as long as the battery remains within typical charge/discharge operating range,the SRAM provides battery-backed storage of information.
