    LTspice simulation of component with different shutdown/startup voltages

    Yes it would, but I never experienced V=0 in my simulation, but I added a condition fixing that. From my simulation it seems to get hung up when the arbritrary current source starts increasing current draw, which in turn changes the input voltage, which causes the V(Vout) of the comparator to...

    LTspice simulation of component with different shutdown/startup voltages

    Thanks! That was what I was looking for, I implemented a comparator circuit with hysteresis but now I'm having another problem. It works with an ideal power supply hooked up to it, but if I add a series resistor between the voltage supply and the circuit thats consuming the load, the simulation...

    LTspice simulation of component with different shutdown/startup voltages

    I have a device that I'd like to model in LTspice for some power analysis, it consumes 24W constant at voltages above 12.5V, and below 12.5V it shuts down. I was able to model this simply with a voltage depend current source and a table of values. However, after it shuts down it doesn't start...

    Connecting SGMII <-> RMII

    I'm looking for the best way to connect a SGMII signal to RMII. Right now I'm using two phys and connecting them via ethernet. Alternatively I found the MAX24287 which can convert SGMII to RGMII, but I'm not certain if RGMII is downwards compatible with RMII. Any advice?
