Fuel gauge operates independently of battery series-cell configurations

Digi-Key is now stocking Texas Instruments' (TI) bq34Z100, a fuel gauge solution that works independently of battery series-cell configurations and features Impedance Track technology. The bq34z100 supports a wide-range of Li-Ion and LiFePO4 battery chemistries. Batteries from 3V to 65V can be supported through an external voltage translation circuit that can be controlled automatically to reduce system power consumption. The device provides several interface options, including an I²C slave, an HDQ slave, one or four direct LEDs, and an alert output pin. Additionally, it provides support for an external port expander for more than four LEDs.
