I'm not seeing the same issue. Ad blocker off and no warnings.

Can I make a contribution to keep the forum going. It will in anyway make big dent in the costs but if it keeps it running for a couple of weeks it would I hope help.

Hi,

I put a scope on the test rig I use to test my boards and ancillaries and looked at the 12V line. I was getting 200mv ripple. You could see the bounce on the wave as the PWM was triggered. ...

Thanks all

Will add the diode

Tim

Hi,

I need to turn on and off a pump. 12v 300ma. Do I need a protection diode on the mosfet? Solenoids etc I add them. Not sure about pumps though.

Thanks

Tim

Thanks everyone

Looking at the delay chips they seem to have short delays in the ns range. I need around 8 ms. Another issue is I need different delays. 8ms, 16ms, 24ms etc one for each fan.

Hi Les

The Freq is 20khz. Also I do not have 5 extra spare pins to drive the fans. I have one line and want to introduce a delay in that line to 5 take offs.

Tim

Ok it was a odd title but it describes my issue.

I have 6 high power 12v fans that can pull up to 2.4amps. They are controlled via a PWM signal that even at the highest level is still a PWM it...

For the sake of a couple of lines of code you prevent a once in 100000 occurrence which in practice will happen a lot more often. If you sell a product one failure will make you regret not adding it.

No matter what you do, you have to check for buffer over run and clear it.

I will have to hunt through my code and memory to figure out what I was using it for so I can see what I have in code.

That would work. I would need to count the lines but the LM1881 or its newer brother can provide the signals to help with that.

I could though use an A/D to do the job instead of a...
