current limiting circuit

i want to design a circuit that limits the current range to provide protection against high current. I want to use a Schmitt trigger in this design. How can I do this? For example, I want to provide protection between 2 amperes and 15 amperes. When the current falls below 2 A, the circuit should...

Hello, I have an application whereby we are sending a 4-20mA signal to an engine controller (engine speed proportional to mA). The test rig has a requirement for throttle blips, which the legacy controller does via a 24V switched output. The new engine controller cannot accept a digital input...

Disclaimer: I'm not an engineer, just a DIY enthusiast. So I have an cheap old plastic SMD LED desk lamp but its battery and circuit board are missing. I want to turn it into a USB powered lamp for my new apartment but I'm not sure of the best way to power it. It has 31 LEDs and the label on the...

Digitally controlling charge voltage with some regulator like Lm317 is a matter of using some resistor and transistor as stated in lm317 datasheet to select from multiple pre defined voltage. But what about choosing output current ? How it can be adjust with digital signals from...

Background: I'm working with an existing motor+driver board with Vin being supplied by a 4.2V LiPo -> TP4056 Charger Protection Board -> Boost Voltage Regulator. I've also got another subcircuit attached to the end of the TP4056 module through another voltage regulator and diode that powers a...

Hi, I am designing a circuit where the output current will be from 500mA and up I would like to have a constant current of 1A at max What would be the best way to attack this problem? is there any IC I can use to achieve this limiting of the current with a constant voltage? Best regards

Hai Friends. The above given is a current limiting circuit one I found from google. https://electronics.stackexchange.com/questions/200716/current-limiting-with-mosfet Can anyone explain how the circuit works?.
