The Texas Instruments bq27441-G1 fuel gauge is a 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 bq27441-G1 battery 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 bq27441-G1 fuel gauge requires connections only to PACK+
(P+) and PACK– (P–) for a removable battery pack or embedded battery circuit. The tiny, 12-pin,
2.50 mm × 4.00 mm, small outline no-lead (SON) package is ideal for space-constrained applications.
