BQ34Z100PW-G1 Datasheet PDF - TI

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 I²C 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.
