Battery ID and Authentication
Analog Devices’ battery identification ICs provide data storage and serial number identification for battery packs. Cyclic redundancy check (CRC) verification provides data integrity during communication. The low voltage 1-Wire® interface of our battery ID ICs enables serial communication on a single battery contact. The 64-bit unique serial number allows multidrop networking and identification of individual devices. Our battery authentication ICs employ hardware-based Secure Hash Algorithm-1 (SHA-1) token authentication. This allows for security without the added cost and complexity of a microprocessor-based system. Battery authentication is performed using a single contact through the 1-Wire interface.
