Title: APPARATUS AND METHOD FOR ELECTRONIC SYSTEMS RELIABILITY
Abstract:
Apparatus and methods for protecting electronic circuits are disclosed. In one embodiment, an apparatus for providing protection from transient signals (14, 16) comprises an integrated circuit (1), a pad (42) on a surface of the integrated circuit, and a configurable protection circuit (22) within the integrated circuit. The configurable protection circuit is electrically connected to the pad. The configurable protection circuit comprises a plurality of subcircuits (72, 74, 76) arranged in a cascade, and selection of one or more of the plurality of the subcircuits for operation determines at least one of a holding voltage or a trigger voltage of the configurable protection circuit.
