The Texas Instruments BQ34Z100 is a fuel gauge solution that works independently of battery series-cell configurations, and supports a wide range of Li-ion and LiFePO4 battery chemistries. Batteries from 3 V to 65 V can be supported through an external voltage translation circuit that can be controlled automatically to reduce system power consumption.

The BQ34Z100 device provides several interface options, including an I2C slave, an HDQ slave, one or four direct LEDs, and an ALERT output pin. Additionally, the BQ34Z100 provides support for an external port expander for more than four LEDs.
