DS2436单片机基本特征描述:
The DS2436 Battery Identification/Monitor Chip provides a convenient method of tagging and identifying battery packs, by manufacturer, chemistry, or other identifying parameters. The DS2436 allows the battery pack to be coded with a unique 64-Bit ROM ID and a 16-Bit Manufacturer ID, and also store information regarding the battery life and charge/ discharge characteristics in its nonvolatile memory.
The DS2436 also performs the essential function of monitoring battery temperature, without the need for a thermistor in the battery pack.A cycle counter assists to determine the remaining cycle life of the battery. Finally, the DS2436 measures battery voltage and sends that measured value to a host CPU for use in end-of-charge or end-of-discharge determination or basic fuel gauge operation. Information is sent to/from the DS2436 over a 1-Wire interface, so that battery packs need only have three output connectors: power, ground, and the 1-Wire interface.
DS2436 FEATURES:
•Unique 1-Wire. interface requires only one port pin for communication
•Provides unique 64-bit identification number to battery packs
•On-board A/D converter monitors battery voltage for end-of-charge and end-ofdischarge determination
•Eliminates thermistors by sensing battery temperature on-chip
•256-bit nonvolatile user memory available for storage of data such as fuel gauge and manufacturing information
•2-byte cycle counter
•Operating range of -40°C to +85°C
•Applications include portable computers,portable/ cellular phones, consumer electronics, and handheld instrumentation
