Description : Single Cell Li-Ion Battery Fuel Gauge for Battery Pack Integration

DESCRIPTION
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.
