The b ui l t- i n featur es of the

r i sk i n m ost cases.
The series resistors on the cell inputs of the
M AX 11080/M AX 11081, as well as the internal
design, ensure protection against random
power-supply or ground connections.

The level-shifted interface design of the
M AX 11080/M AX 11081 ensures that the SHDN,
GND
connected at any time with no load.
The level-shifted interface design of the
M AX 11080/M AX 11081 ensures that the SHDN,
GND
connected at any time as long as the power
bus is properly connected.
A break in the power bus does not cause a
problem as long as there is no load on the
stack.
An AC-coupled bus with isolation on the SHDN
pin or a redundant bus-bar connection should
be used to protect against this case.
