Hello.

How to made short circuit protection (or overcrrent protection fo this circuit)?
I know , to insert a sense resistor between mosfet and ground or load and power supply, and to sense the voltage drop across the resistor, but I don't know how to lower the pwm amplitude with this signal.

Thanks for any help.

Take a look at the attached circuit diagram ..
This idea will require some modifications, but can apply to single MOSFET - Load configuration as well ..

Regards,
IanP
