The BQ34Z100PW is a Fuel Gauge IC, works independently of battery series-cell configurations and supports a wide range of Li-Ion and LiFePO4 battery chemistries. Batteries from 3 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 I?C slave, an HDQ slave, one or four direct LEDs and an Alert output pin. Additionally, the BQ34Z100PW provides support for an external port expander for more than four LEDs.
