Dear all,
I am attaching a drawing containing a circuit simulation for a current sense while using a GPS antenna. I am wondering if you can suggest me a circuit that can switch off (shut down) the circuit after the MOSFET Q3 when a short circuit is provided at load (GPS antenna).
In principle it seems a easy task, but I need the MOSFET Q3 operating normally again when ceasing the short circuit, so I was told about to avoid the "deadlock" situation.
As most as I tried a new circuit, I was never able to get rid off from the deadlock (once the circuit is switched off it cannot back to normal operation).
Can someone please suggest and drop a circuit here ? Thank you in advance.
