Overview

The Texas Instruments bq27411-G1 reference design 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.
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).

Features
  • Impedance Track technology
  • Easy to configure
  • Low BOM count
  • Low power consumption
  • This circuit design is tested and includes orderable EVM, User's Guide, and evaluation software.
