The CN302 is a battery management System-on-Chip (SoC) manufactured by Consonance, specifically designed to provide sophisticated battery management to Li-Ion, Li-Polymer, and other batteries. This 6-pin SOT-23 RoHS-compliant package is the most power-efficient device available, featuring ultra-low quiescent current and strong code protection capabilities. It has excellent self-discharge performance with intelligent clevererecharge, deep discharge, overcharge, and over discharge protections, making it an ideal solution for portable devices. The CN302 is capable of managing single cell or multi-cell batteries (up to 4 series cells) and features adjustable voltage accuracy, allowing users to set the target voltage for high accuracy and reliability. It provides adjustable pre-charge, safety timer, trickle charge, cell balancing, and more. Additionally, the CN302 integrates temperature compensation which reduces battery aging and maximizes battery life.
