My function is to compare and produce an output, whereas one pin will sense the voltage present at instant and give(for eg Vout should be high if the voltage is <3.9 and Vout should be low if Vout is greater than 4.3)
a delay is signal is a signal check for the output source, (irrespective of high or low there signal flow and circuit is complete)
this is my objective

 

Here's the LM339/393 circuit modified with a TL431 reference configured as a series regulator to provide constant 5V power to the circuit.
The LTspice simulation shows the output going low at an ECO voltage of 2.68V and high at 2.33V with each transition delayed about 1 second, for both 12V and 24V power.
Is that what you wanted?

Crutschow thanks for ur help and support.
i have almost completed the circuit and functionality last few query i have in creating the delay in the circuit, rest functionality everything is fine and i could manage it as per requirement.
i will explain my thoughts and ideas...could you just say whether it will be fine.
let me know when ur online.

could you help me in getting model files for Altium designer?

Sorry, I'm not familiar with Altium designer.
