NJW4108
DESCRIPTION
The NJW4108 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, it can be used for a wide range of battery cells for both 1-cell and 2-cell applications. It includes a lot of safety features for safety conscious design: Over voltage, Over discharge, temperature monitor and over charge timers.
