BQ26100DRPR Description

Short technical summary and product information.

The BQ26100DRPR from Texas Instruments is a security and authentication integrated circuit designed for battery pack authentication. It ensures that only authorized sub-contractors' battery packs are used in the end application by employing the SHA-1 hash function within the keyed-hash message authentication code (HMAC) construction. Each device stores a unique 128-bit key for host authentication.

 

This IC features a single-wire, bi-directional SDQ interface operating at 5 kbits/s, reducing communication overhead. It can derive power directly from the communication bus. The operating temperature range is -40°C to 85°C, with a typical input voltage of 5V and a maximum of 7.7V. Typical power consumption is 50mW.

 

The BQ26100DRPR is housed in a 6-lead VSON package with exposed pad, measuring 3mm x 3mm. It includes 160 bytes of one-time programmable (OTP) memory and 16 bytes of EEPROM. The device also features an internal time-base, eliminating the need for an external crystal oscillator. Low-power modes include Active mode (<50 µA typical) and Sleep mode (8 µA typical).

 

This component is suitable for applications requiring secure battery pack identification and authentication, ensuring product integrity and preventing the use of unauthorized components.
