Hey Guys,
I was simulating circuit to meet below requirement.
Vin<18V, Vout=0V
18V>Vin<30V, Vout=Vin
Simulation it works in ltspice but i see problem about VGS of MOSFET follow the input voltage and hence it can damage the mosfet.
I tried adding zener in the gate of MOSFET but it did not work as expected. Also if make opamp supply using zener even same problem i see.
Can anyone help me here .
How to reduce VGS value.
No other power supply will be used and we have to use input voltage eg. 5V to 30V.
Thanks in Advance !
