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.
