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.
