Description

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.

An evaluation kit is available:  DS2436K  

Key Features		Applications/Uses
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-of-discharge 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		Consumer Electronics Handheld Instruments Portable Computing Portable/Cellular Phones
