Programmable current-limit/e-fuse (+current monitoring?)

Short version: How best to make either a current limiting circuit or an e-fuse (both options are fine to me) so that I can set the limit from software (and not through a fixed resistor as usual)? ...

Is there a better way to protect my power supply other than the efuse?

I use fairly cheap standard power supplies with no protection in my circuit experiments, usually with output of 5V, 12V, 18V, 30V and a current up to 1A. I use standard glass fuses to protect these ...

First time designing an SR latch; I'm using it to control the enable pin on my eFuse IC. Just want to know if I'm overlooking anything

I just finished designing my rectifier module that has a built-in voltage monitor IC and an eFuse IC. Its purpose is to convert the 3-phase AC output from my wind turbine and use it to power my USB ...

What op-amp should you use for an electronic fuse?

I am trying to design an electronic fuse. The circuit is powered at 24V and the fuse should disconnect the circuit when there is a current greater than 11A. Searching the internet, I found several ...
