Hi gnurf,
Thank you for the articles, they are very good. Do you know how I can do the same thing but with discrete components?
I tried to improve the previous circuit, in order to switch off the mosfet, but without good results. You can find attached the circuit.
Thank you
Hi,
Beside this current limitation, I would like also, to shut down the circuit when current becomes equal or higher than 1A.
If you could give me some ideas how to do it, I would appreciate it.
Thank you
Hi,
under normal conditions transistor Q1 is blocked. R2 is used to sense the current through it. When current is 1A, the voltage drop over R2 is 0.7V and Q1 is turned on, which in turns increase the voltage on the gate of M1, and keep it at the limit of conduction.
R4 is used to limit the...
Hi,
I made a current limit protection circuit at 1A, and I would like to improve it with an overload protection.
Could you give me please some ideas how to switch off the mosfet when the load current exceed 1A?
Thank you
