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 ...

Power-supply failure takes on significant importance in high-end computer, telecom, medical, and industrial applications, in which uninterruptible power is paramount. In these systems, diode-OR-ed ...

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

POWER OVER ETHERNET (POE) enabled devices and their electronic components are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or ...

When we get a new device these days, somewhere in the package is likely to be a wall-wart USB power supply. We look for a place to plug in the little switch-mode dongle, rearrange a few plugs in the ...
