The BQ34Z100PW-G1 is a stand-alone multi-chemistry impedance track Fuel Gauge/battery Gas Gauge. It is an Impedance Track™ fuel gauge for Li-ion, PbA, NiMH and NiCd batteries with work independently of battery series-cell configurations. Batteries from 3 to 65V can be easily supported through an external voltage translation circuit that is controlled automatically to reduce system power consumption. The BQ34Z100-G1 device provides several interface options, including an I?C slave, an HDQ slave, one or four direct LEDs and an ALERT output pin. Additionally, the device provides support for an external port expander for more than four LEDs.
