Protecting Industrial Digital Control Outputs Using Intelligent MOSFETS
PDF, 55 Kb, File published: Oct 26, 2000
Digital outputs in industrial applications often must implement some type of protection measure. The integrity of the signal, transmitted over a distance of several meters, can suffer due to fault conditions like a short circuit or an overcurrent, either of which can damage the device driving the signal. To prevent electromagnetic compatibility problems, it may also be necessary to slow down the s
