I am using a mc41 for my application, my application is led control with the cout, but is it possible to do this, so my Leds can be dimmed?
IMHO, I don't think you will have much luck doing this. If you read specs, a the minimum load a COUT will work with properly is 100 mA. A individual LED only needs 10 mA at full brightness. Any current over 20 mA will cause a LED to fail. You will need a series current limiting resistor as well as a separate load resistor, to be wired in parallel with the LED and current limiting resistor. And, after you've done this, you may note that the amount you can vary the brightness is VERY limited. You should define the output as a PWMout, not COUT, for best results.
I've been working with IQAN products for 12+ years, so have been there, done this. I would suggest wiring something up on your bench first to check this out and see if it's acceptable.
Theleo, did you ever solve this. Have a similar application
I have solved this problem. I have used a PWMout instead of a Cout. It now works prefectly. There is just one tiny thing, the leds will shine a bit. Even when the PWMout is 0%. This is because of the constant measuring for a lost in resistance.
