Description for the BQ27350

The Texas Instruments' bq27350 is a battery fuel gauge with secure authentication support for single cell Li-Ion/Li-Polymer battery packs. Designed for battery pack integration, the device requires little host microcontroller firmware support for implementation. The system host processor communicates with the bq27350 over an I²C interface to obtain remaining battery capacity, system run-time predictions, and other critical battery information.

The bq27350 uses the patented Impedance Track™ algorithm for its fuel gauging. 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 bq27350 also features both integrated and external support for secure battery pack authentication, using the SHA-1/HMAC authentication algorithm.
