GENERAL DESCRIPTION
The DS25LV02 provides data storage and serial
number identification for battery packs. The low-
voltage Dallas 1-WireÒ interface enables serial
communication on a single battery contact and the
64-bit
networking and identification of individual devices.
The 1024-bit EPROM memory is organized as 4
pages of 32 bytes each and supports storage of
battery cell characteristics, charging voltage, current
and temperature parameters, as well as battery pack
manufacturing data. CRC verification provides data
integrity during communication. The EPROM pages
are in-circuit writable and can be individually locked
to protect data. The DS25LV02 is designed to be
completely backward-compatible with the DS2502 for
existing designs.
