So I'm working on a circuit that has a PWM input signal and my goal is to control a 24V relay coil.
So when the filtered voltage on the PWM drops below 18V (Vref) I want to energize the coil. But the issue is when I add the coil in the ouput of U1 remains hi.
Also I'm not familiar with the strobe and offset signal, so I left them open, what are those really used for?
