DESCRIPTION
The Texas Instruments bq27411-G1 is an easy to
Powered directly from battery with
configure fuel gauging solution for single series cell
integrated LDO
Li-Ion battery packs. The device requires minimal
400-kHz I2C serial interface
configuration and uses One Time Programmable
Internal temperature sensor, or
(OTP) Non-Volatile Memory (NVM) to avoid an
Host reported temperature
initialization download by the system processor.
Easy to configure fuel gauging based on
The bq27411-G1 uses the patented Impedance
patented Impedance Track™ technology
Track™ algorithm for fuel gauging, and provides
information
