Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

I use an old ATX PSU as a bench supply for my projects and needed a simple & cheap adjustable current limiting circuit. I use an old ATX PSU as a bench supply for my projects and needed a simple & ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...
