Description

The NJW4100 is a Lithium-ion Battery Charger Controller IC with over charger timer.

Charger current and voltage can individually be set by the external resistors. Therefore, NJW4100V  can be used for a wide range of battery cells for both 1-cell and 2-cell applications.

NJW4100V includes a lot of safety features for safety conscious design: Over voltage, Over discharge, temperature monitor and over charge timers.
