The Texas Instruments bq27425-G2 fuel gauge is an easy-to-configure microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries. The device requires minimal user configuration and system microcontroller firmware development.

The fuel gauge 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-G2 fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable battery pack or embedded battery circuit. The 15-pin, 2.69 mm × 1.75 mm, 0.5-mm pitch chip scale package (DSBGA) is ideal for space-constrained applications.
