Electronic fuse for protecting the output stage transistors of an amplifier

摘要

Electronic fuse for protecting the output stage transistors of an amplifier, particularly of the output of an AF output amplifier. Insertion of a capacitor (C4) between two stages (T4, T5) present in any case creates a monostable flip flop which produces a short switch-on time (T1) and a long switch-off time (T2) in the case of a fault. <IMAGE>
