Abstract

Protective device for integrated circuits, characterized essentially by the provision of a discrete transistor associated with one of the transistors belonging to the integrated circuit to be protected, with which it forms a differential amplifier, current limiter having both its emitters joined together and to the source of current in order that said electrodes remain at a negative potential with respect to the output mass, while the base of the integrated transistor is connected to the cursor of a potentiometer belonging to a voltage divider and which also communicates a negative polarization with respect to the mass of the output, while the base of the discrete transistor is attached to the input of the mass of the unregulated source. Whatever the circumstances that concur in the essentiality of the utility model, defined in the previous claim whose purpose is. (Machine-translation by Google Translate, not legally binding)
