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.
