... Charging Lithium Cells The lithium cells must be charged with a dedicated charging IC such as the NE57600. These dedicated charging ICs perform a current-limited, constant-voltage charge, as shown in Figure 7. The charger IC begins charging with a current that is typically the rating of the cell (1C) or the milliampere rating of the cell. As the cell ...

... One-cell Lithium-ion battery protection with over/undercharge and overcurrent protection APPLICATION INFORMATION The NE57600 drives the series N-Channel MOSFETs to states determined by the cell’s voltage and the battery pack load current. During normal operation, both the discharge and charge MOSFETs are ON, allowing bidirectional current flow. ...
