Claim:
1. A fault detection assembly of an integrated circuit having a supply port, an input port and a ground port, the fault detection assembly comprising: a first diode connected with one end to the supply port and connected with another end to the input port; a second diode connected with one end to the input port and connected with another end to the ground port; at least a first fault detection transistor of MOS type; wherein at least one of first and second diodes comprises a first diode-connected MOS transistor whose gate is connected to the gate of the first fault detection transistor, and wherein one of drain and source of the first fault detection transistor is connected to the input port and the other one of the first fault detection transistor's drain and source is connected to a first resistor connected to one of supply port and ground port.
