I know how undervoltage circuit works. i am simulating this circuit to check if my design works fine and for that i have to create momentary underoltage condition at load side.

I have an undervoltage circuit which senses load voltage. If load voltage decreases from specific value it starts working. Now i want to simulate it in orcad to see if it works fine. But i have no idea how to decrease load voltage to cause undervoltage condition which triggers the circuit.

I want to simulate an undervoltage circuit. How can i simulate load side voltage so that it decreases after some time to create undervoltage condition?

Hi i want to change this circuit by using low side nmos switch. What changes i have to make in circuit and design equations? LT1389_0699_Mag.pdf
