bq34z100-G1 Wide Range Fuel Gauge

Texas Instruments bq34z100-G1 Wide Range Fuel Gauge is an Impedance Track™ fuel gauge for Li-Ion, PbA, NiMH, and NiCd batteries. It works independently of battery series-cell configurations. Batteries from 3V to 65V can be easily supported through an external voltage translation circuit. The translation circuit is controlled automatically to reduce system power consumption. The bq34z100-G1 provides several interface options. These include an I 2 C slave, an HDQ slave, one or four direct LEDs, and an ALERT output pin. Additionally, the bq34z100-G1 provides support for an external port expander for more than four LEDs.
