How to Build a Timer Circuit Outputting 1V for 10 Minutes Every Hour?

hey guys, I have been doing a timer circuit and i have realized that i need a timer circuit that can give 1V for a time duration of 10 minutes in every hour. How this can be achieved have become a nightmare to me. Help me out.Much Thanks.

I believe the LTC6991 (from Linear Tech, now Analog Devices) will meet your timing requirements using only 1 SMD chip and several resistors and capacitors. (https://www.analog.com/en/products/ltc6991.html#product-overview ). Look for the web based design tool link in the data sheet (although I did find the tool itself to be a little confusing).

However, you will have to add some kind of level shifter/driver for you 1V output depending on your load.

You're better off doing this digitally. Use the mains frequency (you can take rectified but unsmoothed DC, limit it and square it). This will give you 50, 60, 25 or 30Hz pulses (depending on your mains frequency and whether you full or half wave rectify). Divide that down further to give you one pulse per 10 mins. Then divide those by 6 and detect one unique state, that will give you one 10-minute pulse per hour.
You could use discrete logic for this (the 7492 has a divide by 6 counter and the 7490 is divide by 10), or use a microcontroller and use the counter(s) to do it.

Hi
You can build a current constant circuit.
In this mode, the voltage on te output is proportional to the time.
Take care, for high time you need high voltage.

hello
I have had a look at this reply you have shared and below is the screenshot of what I have seen. I need a timer that shares 1v every 10 minutes. This one seems to share it every 1minutes. I also don't see the 555 timers. The timer am talking about is in the link below

Hi Aubrey,

What did you do to resolve the issue?
