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

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

Texas Instruments bq27411-G1 Single Cell Li-Ion Battery Fuel Gauge that 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). The small 12-pin 2.5mm × 4mm SON package is ideal for space constrained applications.
