Impedance Track is a trademark of Texas Instruments.
I2C is a trademark of Phillips Corporation.

The Texas Instruments bq27541 Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development for accurate battery fuel gauging. The bq27541 resides within the battery pack or on the system’s main-board with an embedded battery (nonremovable).

The bq27541 uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), run-time to empty (min.), battery voltage (mV), and temperature (°C).

The bq27541 also features integrated support for secure battery pack authentication, using the SHA-1/HMAC authentication algorithm.
