A 1024-Bit EPROM Memory that Operates from a Supply as Low as 2.2V, Compatible with a 1.8V I/O Supply Rail, and Backwards-Compatible with the Industry-Standard DS2502 Battery Pack ID
The DS25LV02 provides data storage and serial number identification for battery packs. The low-voltage Dallas 1-Wire® interface enables serial communication on a single battery contact and the 64-bit unique serial number allows multidrop 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.
