SC8933 Overview
SC8933 is a synchronous buck charger with reverse boost discharging function. It integrates two N-channel MOSFETs with ultra-low Rdson and can support up to 12V high efficiency charging and discharging operation. In charging mode, it steps down the input voltage to effectively charge the single cell battery.
