ABSTRACT:
An ESD protective circuit protects an input or output of a monolithically integrated circuit. The ESD protective circuit has at least one bipolar transistor structure and one ESD protective element between two supply networks. The emitter of the bipolar transistor structure is electrically connected to the input or output, while the base is electrically connected to one of the two supply networks. The collector produces a current signal, which is used for triggering of the ESD protective element, when an ESD load occurs at the input or output.
