Web6 de jul. de 2024 · Assumed that the opamp output voltage is at positive saturation (Vsupp) for an ideal case. Then all you need to do is to find the Vin value for which the voltage at non-inverting is exactly equal to Vred = 2V. Case 2 The opamp output voltage is at negative saturation (OV for your circuit). Web21 de set. de 2016 · The circuit sees enough voltage and turns the heater back on. Hysteresis to the rescue: cut off the load once voltage drops below 11.5V and do not turn back on until it's above say 11.8V. Problem is, I have NO idea on how to implement something like that. Is that even doable with the attached subcircuit? Sorry for the sucky …
