bq27411-G1 Single-Cell Li-Ion Battery Fuel Gauge

The Texas Instruments bq27411-G1 device is a battery fuel gauging solution for single-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 fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and.
