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.
