DS2434单片机基本描述:
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.
DS2434 FEATURES:
·Provides unique ID number to battery packs
·Eliminates thermistors by sensing battery temperature on-chip
·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.
·Surface-mount package (209-mil SSOP16)available
