■PIN CONFIGURATION
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, 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.
