SC8813 Overview
SC8813 is a synchronous buck charger controller with reverse boost discharging function. It supports very wide input and output voltage range, suitable for applications of 1 to 4-cell Li-ion battery. In charging mode, it steps down the input voltage and effectively charging the batteries as long as the input voltage is higher than battery voltage.
