Description for the BQ27425-G1
The Texas Instruments bq27425 system-side LiCoO2 battery fuel gauge is an easy to configure microcontroller peripheral that provides fuel gauging for single-cell LiCoO2 battery packs. The device requires minimal user configurations and system microcontroller firmware development for accurate fuel gauging.
The bq27425 uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV).
Battery fuel gauging with the bq27425 requires only PACK+ (P+), PACK– (P–), for a removable battery pack or embedded battery circuit. The 15-pin 2,69 × 1,75 mm, 0.5 mm pitch CSP package is ideal for space constrained applications.
