Abstract
The battery protection integrated circuit includes: a higher-level reception terminal configured to receive information from a higher-level circuit; a lower-level transmission terminal configured to transmit information to a lower-level circuit; a storage configured to store a unique identification information; a higher-level signal input terminal configured to be supplied with a permission signal; a lower-level signal output terminal configured to output a second permission signal to the lower-level circuit; a storage controller configured to store a unique identification information when the identification information is not stored, and when the permission signal is supplied; and a switch configured to make the lower-level signal output terminal not provide the second permission signal when the identification information is not stored in the storage, and make the lower-level signal output terminal provide the second permission signal when the identification information is stored in the storage.
