Description
AI
The BQ34Z100-G1 device is an Impedance Track™ fuel gauge for Li-ion, PbA, NiMH, and NiCd batteries, and works independently of battery series-cell configurations. Batteries from 3 V to 65 V 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 anALERToutput pin. Additionally, the BQ34Z100-G1 provides support for an external port expander for more than four LEDs.
