Bq26100 IC Batt Authorization Chip

BQ26100 is a battery protection IC launched by Texas Instruments in 2006, mainly used for the protection and management of lithium-ion batteries.
Portable electronic products, smart home, electric tools, electric vehicles and other fields can effectively protect the safety and stability of lithium-ion batteries and prolong battery life.
At the same time, BQ26100 also supports I2C interface, which is convenient for communication and control with other devices such as MCU.
In addition, BQ26100 can also be widely used in battery power monitoring, battery charging management, battery protection, power management, battery information storage, battery balance management, and monitoring the status of power packs.
In addition, BQ26100 has identity authentication function. It can verify the authenticity of the battery pack by using the SHA-1 hash function. Each BQ26100 device stores a unique 128-bit key that allows the host to authenticate each packet.
These verifications include certificate-based authentication, digital signatures, and key-based authentication. This is a strong authentication mechanism that can be used to protect devices and data. Certificate-based authentication uses certificates to verify the identity of a device or user. Certificates are digital certificates that contain a device or user's name, public key, and other information. A device or user presents a certificate to a server, and the server uses the public key in the certificate to verify the identity of the device or user. This is a technique that can be used to verify the integrity of data. Digital signatures use private keys to create digital signatures that can be used to verify that data has not been tampered with. If the data has been tampered with, the digital signature will not match the data and the server will reject the data.
At present, our company has fully mastered these technologies and can assist customers in developing applications and completing identity verification functions. Welcome to cooperate and exchange.
