DESCRIPTION  
The Texas Instruments bq27411-G1 is an easy to  
configure fuel gauging solution for single series cell  
Li-Ion battery packs. The device requires minimal  
configuration and uses One Time Programmable  
(OTP) Non-Volatile Memory (NVM) to avoid an  
initialization download by the system processor.  
Powered directly from battery with  
integrated LDO  
400-kHz I2C serial interface  
–
–
Internal temperature sensor, or  
Host reported temperature  
•
Easy to configure fuel gauging based on  
patented Impedance Track™ technology  
The bq27411-G1 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).  
–
Reports Remaining Capacity and State of  
Charge (SOC) with Smoothing Filter  
–
Automatically adjusts for battery aging,  
self-discharge, temperature, and rate  
changes  
The small 12-pin 2.5 mm × 4 mm SON package is  
ideal for space constrained applications.
