Abstract
The present invention is directed towards a discrete protection circuit located on a circuit card, and systems and methods related thereto. The protection circuit protects circuit card components from an inrush current and overcurrent conditions. The discrete protection circuit includes a switch to control a delivered load current to an output port, an SCR which latches when an overcurrent condition is detected across a sense resistor, and a series of resistors and a capacitor that determines the retry delay subsequent to an overcurrent detection. Advantages of the discrete protection circuit of the invention over prior art integrated circuits include: lower parts counts, lower production costs, greater flexibility, and increased reliability.
