I'm looking at an application that needs to pass 8A during normal operation yet trip at 8.5A. The LM5069 would seem close but the tolerance of the current limit threshold voltage is 48.5 to 61.5mV. In order to make sure 8A is always passed I'd have to design to roughly (.0485/8) = .006 ohms. The max the part could then trip at is (.0615 / .006) = 10.25A.
Are there any other parts that pull the tolerance in or are the design requirements unrealistic?
