OVERVIEW

The 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.
