DescriptionThe Texas Instruments bq27411-G1 device is a battery fuel gauging solution forsingle-cell Li-Ion battery packs. The device requires minimal configuration and uses One TimeProgrammable (OTP) Non-Volatile Memory (NVM) to avoid an initialization download by the systemprocessor.
The fuel gauge uses the patented Impedance Track? algorithm for fuel gauging, andprovides information such as remaining battery capacity (mAh), state-of-charge (%), and batteryvoltage (mV).
The small, 12-pin, 2.50 mm × 4.00 mm, Small Outline No-Lead (SON) package is ideal forspace-constrained applications.
