Introduction

AI Translation

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 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.
