NE57606
2 to 4 cell redundant Lithium-ion overcharge monitor

APPLICATION INFORMATION
The NE57606 can be used within 2, 3, or 4-cell battery packs. This
can be done by electrically creating a short-circuit across the pins
that would have been connected to the ends of the cells. For a 3-cell
pack pin VC1 should be connected to ground (pins 3 to 4). All of the
combinations are shown in Table 1.
