Single-Cell Battery Fuel Gauge Debuts As Smallest

Claiming to be the smallest available, the bq27505 single-cell battery fuel gauge IC with Impedance Track technology measures 2.5 mm x 2 mm x 0.625 mm and supports portable applications such as smart phones, digital cameras, and MP3 players. Described as an accurate and complete battery fuel gauge, the CPU-based device reports remaining capacity, time-to-empty, voltage, current, temperature, and calculates remaining charge under all conditions. Additionally, it provides complete state-of-health battery data so a system can effectively manage the battery and extends run-time plus no calculations are necessary with the host microcontroller. Other features include a display of run time under all conditions and no extra circuitry is needed inside the battery pack. Price is $1.45 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX.
