Abstract: An integrated circuit, current protection network wherein the point of operation (trip point) can be changed over a wide range of values by proportioning the areas of the junctions of semiconductor devices. A pair of transistors form a high gain differential amplifier, with the emitter electrodes of the transistors connected to the ends of a sense resistor through which current flows to the device to be protected. Diodes are connected between the base and emitter electrodes of the two transistors with the same polarities as the junctions, so that the current flow through the transistors will be in accordance with the areas of the junctions of the transistors and diodes. During construction of the integrated circuit, the areas of the junctions can be selected to provide the desired trip point for the network. A differential to single ended converter load circuit is connected to the collector electrodes of the transistors, and controls the protected device when the trip point is reached.
