Description

technical field

[0001] The invention belongs to the technical field of semiconductor bridge pyrotechnics, and in particular relates to an integrated semiconductor bridge transducing element. Background technique

[0002] Semiconductor bridge pyrotechnic products are widely used in ignition and detonation systems of weapon systems and civilian blasting equipment due to their excellent quality. At the same time, with the increasingly harsh electromagnetic environment, the requirements for the anti-electromagnetic environment capability of semiconductor bridge pyrotechnic products are also getting higher and higher. For example, for its safety, it is generally required to achieve 1.A.1W.5min insensitivity or higher insensitivity, and for its reliability, its reliability is generally required to be 0.995-0.9999 (confidence level 0.95). Existing semiconductor bridge chips have been difficult to resist external electromagnetic field energy interference in harsh electromagnetic en...
