NJW4124 Overview
Description
NJW4124 is a 1-cell and 2-cell lithium ion battery charge control IC with a built-in AC-DC secondary side control feature. Using a photocoupler to directly feed back optimum charging voltage and current information to the primary side, it increases energy efficiency, makes possible a smaller charger, and conserves energy.
