Humpawumpa I added the schematic. This cd4093bcn datasheet clearly spelled out in the datasheet. A will not work. Datasjeet am trying to design a circuit using an intermitent power source a bicycle hub generatorwhich is rectified and filtered, cd4093bcn datasheet regulated at 6,8V. Change R4 to alter the hysteresis.

Flip a Schmitt-Trigger when current flows through a Zener cd4093bcn datasheet. I have one around. Also, do I assume correctly cd4093bcn datasheet altering the proportion beetween R6 and R5 I could tune the values of the cd4093bc voltage thresholds? Post as a guest Name.

Could you elaborate on that? Regarding the circuit with the Schmitt trigger, note that the levels of the Schmitt trigger are relative to the supply voltage so it is chasing cd4093bcn datasheet moving target the trigger cd4093bcn datasheet moves up as the supply goes up. How could I properly activate the Schmitt trigger when the Zener is “on”?

The trig buffer means dattasheet IC properly connected to power rails. I noticed you exchange the position between the Zener and its cd4093bcn datasheet resistor. Yes, you can use an LM, it will work about as well in the above circuit, but put a 10K in parallel with the LED to keep the hysteresis about the same. Thanks for your answer!

It’s the dual version of the quad LM that Bimpelrekkie used. If the input cd4093bcn datasheet is Vcc – 6. Pardon my lack of knowledge, but could you please tell me datadheet the doesn’t work? If you could the Schmitt cd4093bcn datasheet input to ground then that stays constant as the trigger level changes with the supply.

If you derive the supply from the input voltage you have to take that into account. R7 is optional it adds a bit of hysteresis like cd4093bcn datasheet the Schmitt triggers.

Questions Tags Users Badges Unanswered. Datashewt needs more supply voltage and the input common mode range does not include ground. The circuit presented datasheeh electronics.

What am I doing wrong?

It is not what you need. This might work, what zener value you need I do not know, I would experiment a little. Could you provide a schematic of the schmitt trigger variant as well?

The Schmitt cd4093bcn datasheet ICs have rather cd4093bcn datasheet defined thresholds that are percentages of the supply voltage, not absolute cd4093bvn. I made the zener voltage of D1 a bit lower, now the LED should switch on above 6.

Make R7 smaller to increase the distance between the trigger levels. It would cd4093bcn datasheet very useful to me, thanks! I made a mistake and the trigger output is “sinking” the led instead of “sourcing” it, cd4093bcn datasheet the overall intention is preserved: I did’nt understand your inversion.

cd4093bcn datasheet You can try something like this, which uses half of an inexpensive dual op-amp as a comparator. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Is there a datasheeh to know if any other OpAmp cd4093bcn datasheet work or not, cd4093bcn datasheet are there a set of characteristics that would guide me to choose a fitting OpAmp for this application?

The LM is likely the cheapest op-amp in the world maybe a penny or two in volume datasgeet is suited for this application, especially the wide supply range. In my 2nd circuit the zener makes a reference voltage, let’s assume it is 3 V.
