Crowbar circuits are so-called because their operation is the equivalent of dropping a crowbar (large steel digging implement) across the terminals. It is only ever used as a last resort, and can only ...

Altech Corporation, a developer of industrial automation solutions, announces the release of DFS F Audio residual current ...

This is just an ultra-quick blog post about a nostalgic IC: µPC1237. It’s a timeless bipolar analog IC from NEC designed for protecting stereo audio power amplifiers and loudspeakers. I used to see ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...
