This overvoltage protection or crowbar protection circuit is used where we need protection against high voltage surge. The circuit has a few components, it is very easy to build and will protect your ...

Designers often test prototypes with a variable-voltage bench power supply. If they leave the bench for any length of time, someone may borrow the supply or otherwise change the voltage to a level ...

For the JPEG version of this article, click here. Sensitive circuits are prone to failure if stressed by overvoltage transients. In some cases, the damage can be extensive and expensive. The source of ...

Design engineers often give circuit protection only cursory attention. For example, fuses, diodes, and varistors are so well known that designers select them with ...
