Maxim's 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.
