DESCRIPTION

The Texas Instruments bq34z110 is a fuel gauge solution that works independently of battery series-cell

configurations, and supports Lead-Acid battery chemistries. Batteries from 4 V to 64 V can be supported through

an external voltage translation circuit that can be controlled automatically to reduce system power consumption.

The bq34z110 device provides several interface options, including an I²C™ slave, an HDQ slave, one or four

direct LEDs, and an Alert output pin. Additionally, the bq34z110 provides support for an external port expander

for more than four LEDs.
