Texas Instruments  BQ27411DRZR-G1C

The 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.
