DESCRIPTION
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.

FEATURES
■ Provides unique ID number to battery packs
■ Eliminates thermistors by sensing battery temperature on-chip
■ Elapsed time counter provides indication of battery usage/storage time
■ Time/temperature histogram function provides essential information for determining battery self-discharge
■ 256-bit nonvolatile user memory available for storage of user data such as gas gauge and manufacturing information.
■ Operating range of -40°C to +85°C
■ Applications include portable computers, portable/cellular phones, consumer electronics, and handheld instrumentation.
