Description for the BQ27441-G1

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.
