NE57606
2 to 4 cell redundant Lithium-ion overcharge monitor

Using the NE57606 within a Li-ion battery system
A Li-ion and Li-polymer 4-cell battery system using the NE57605
and the NE57606 is shown in Figures 3 and 4.
The circuit in Figure 3 shares the charge MOSFET between the ICs.
This is sometimes not acceptable since a failure of the charge
MOSFET or its associated drive circuitry can disable protection
provided by the second circuit.
