I am using a P channel MOSFET switch on high side to switch +60V to a load. Current is sensed by a low side shunt resistor.
Suppose the load current shoots up by short circuit in load I need to switch off the MOSFET to save it and other circuitry.
How much time is available to me for ADC reading, processing and to switch off the MOSFET to save itself and other parts?
Hoe fast should be my software based short circuit protection?
Thanks a lot
