DESCRIPTION

The Texas Instruments bq28z560-R1 device is a battery gas gauge with current and voltage protection, and

secure, SHA-1/HMAC authentication for single-cell Li-Ion battery packs. Designed for battery pack integration,

the bq28z560-R1 requires host microcontroller firmware support for implementation. A system processor

communicates with the bq28z560-R1 using one of two options: an I2C™ serial interface or an HDQ single-wire

configuration to obtain remaining battery capacity, system run-time predictions, and other critical battery

information.

The bq28z560-R1 uses the accurate Texas Instruments Impedance Track™ gas gauging algorithm to report the

status of the cell. The gauge provides information such as state-of-charge (%), run-time to empty (min.), charge

time to full (min.), battery voltage (V), and pack temperature (°C).

The bq28z560-R1 features integrated support for secure battery pack authentication, using the SHA-1/HMAC

authentication algorithm.
