DS25LV02 Low-Voltage 1024-Bit EPROM www.maxim-ic.com GENERAL DESCRIPTION The DS25LV02 provides data storage and serial number identification for battery packs. The lowvoltage Dallas 1-WireÒ 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 voltag.

DS25LV02 Low-Voltage 1024-Bit EPROM www.maxim-ic.com GENERAL DESCRIPTION The DS25LV02 provides data storage and serial number identification for battery packs. The lowvoltage Dallas 1-WireÒ 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 www.DataSheet4U.com 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. FEATURES § § § § § § § 128 Bytes of EPROM Storage Organized into Four Separately Lockable Pages Backward-Compatible with DS2502 Dallas 1-Wire Interface Input Logic Thresholds Compatible with 1.8V I/O Supply Rail Unique 64-Bit Serial Number Operates with VDD as Low as 2.2V Tiny, Thin SOT-23 Package PIN CONFIGURATION TOP VIEW APPLICATIONS Cell Phones/Smartphones Digital Cameras MP3 Players TYPICAL APPLICATION CIRCUIT 5-Pin Thin-SOT (TSOT) ORDERING INFORMATION PART DS25LV02R+U DS25LV02R+T& R TEMP RANGE PIN-PACKAGE 5 Thin SOT 5 Thin SOT in Tape-and-Reel -30°C to +85°C -30°C to +85°C +Denotes lead-free package. 1-Wire is a registered trademark of Dallas Semiconductor.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device. RECOMMENDED DC OPERATING CONDITIONS (2.2V £ VDD £ 5.5V, TA = -30°C to +85°C.)
