Battery Identification Chip With Time/Temperature Histogram

The DS2435 Battery Identification Chip with Time/Temperature Histogram provides a convenient method of tagging and identifying battery packs by manufacturer, chemistry, or other identifying parameters. The DS2435 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 DS2435 performs the essential function of monitoring battery temperature without the need for a thermistor in the battery pack. A time/temperature histogram function stores the amount of time that the battery has been in one of its eight user definable temperature bands, allowing more accurate self- discharge calculations to be carried out by the user for determining remaining battery capacity. The on- board elapsed time Counter provides a method that CAN even determine the amount of time that a battery pack has been in storage, allowing for a more accurate self-discharge determination.
