Abstract
The invention relates to an integrated electrical and/or electronic system having at least one functional module connected to a supply voltage and connected via a pin external to the functional module or the electrical system by an electrical terminal. The system may include an isolation device for electrically isolating the functional module, including a fuse whose first pole is connected to a pin of the functional module and the second pole that corresponds to the external electrical terminal, and a semiconductor dipole that can be energized by a priming voltage. A first pole of the semiconductor dipole is connected to the first pole of the fuse and the second pole is externally accessible. A second dipole whose first pole is connected to the pin of functional module and the second pole, is connected to a preset voltage, so that application of a sufficient isolating voltage relative to the priming voltage between the second pole of the fuse and the second pole of the energizable semiconductor dipole causes fuse to physically break, and, thereafter, via a preset voltage on the pin is exclusively maintained which enables the voltage enabling the operation of the functional module to be controlled.
