NJW4120 Lithium-ion Battery Charger Controller IC With Timer

The NJW4120 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. Charging current CAN be freely set and therefore it is possible to optimize charging according to battery capacity.As safety features it has over voltage, over discharge,temperature detection, and a charge over Timer Also, the adaptor and the charge control circuit are mounted on one chip.
