8.3.3 Wiring nFAULT as Wired OR
Since nFAULT is an open drain output, multiple nFAULT outputs can be paralleled with a single resistor. The end result is a wired OR configuration. When any individual nFAULT output goes to a logic low, the wired OR output will go to the same logic low. There is no need to determine which device signaled the fault condition, as once they are connected in parallel they function as a single device.
