Hi,
Can you help me how to design a circuit to monitor the voltage at the MOSFET source terminal?.
Can you help me how to design a circuit to monitor the voltage at the MOSFET source terminal?.
It is always 0v GndI want to monitor the voltage at the source terminal of the MOSFET.
Yes, I know that, but, I want to implement some circuit between the drain source and ground, to monitor the voltage. As I know, shall I put the shut resistor between the MOSFET and GND, so that we will measure the voltage, Right?. See below circuit. Please let me know is it correct or wrong and give me some suggestions if I'm wrong.It is always 0v Gnd
Update:
You originally posted the drain of MOSFET is 24V and current is passing through is 1A.
This is what your LTS sim shows.
That is example circuit which I have attached above. I want to design a circuit which will read the voltage 24V.hi,
Using a 1R Shunt will give a Vout of around of only 120uV.
After a 2:1 divider half that.
Why do you need to know the Source current and how are you going to use the 120uV signal.??

Yes, yes.. I got it why he get angry. Sorry for that mistake.Look at what your divider is connected to. How can that be anything other then 3.3V?
Edit: Hint, unless there is a series resistance on the 24V source, it's terminal is always at 24V.
