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.
