Micron MR603a query

[collectors]

Was looking to switch a few led’s “5” from a Micron MR603a. It seems i can only take about 1 led off any of the P terminals ?"Is that correct" . So no problem I will fit a FET buffer that will give up to 2 amps.
Q 1, Is P 3 & 4 terminals momentary in that push a button & 3v is on, release the same button & is off or 0v. ?
Q 2, Will a FET buffer latch on with a 3v momentary switch. IE: Is it latching?
If none of the above, what terminal do I use as a simple on/off switch for the FET.
Thanks

Are any of these LEDs to be automatically switched for direction?

F1 & F2 can sink a couple of Amps, and are automatic, by direction.

F4 can also sink a couple of Amps, and is toggled on & off with the Bind button.

Does that help you?

F4 can also sink a couple of Amps, and is toggled on & off with the Bind button. Ah! So is the F4 pre programmed to latch. IE: press & release bind once F4 is on, press again & its off.

Does that help you? Thankyou, Yes.

You got it..

F3 can also sink 2Amps, and is momentary, when the Bind button is pressed, it is 'on'..

Hi, thanks for the help, but i get lost with electronics terminology. "F3 can also sink 2Amps" i take it means F3 can take a load of 2 Amps" Also i am wondering why Micron says a sink/load of: "(P1..P6), 0V when off, 3.3V when on, max 20mA" Or is this 2amp just momentarily & not constant.

I think you''re confusing your Fs and Ps. The F outputs are FET buffered to 2A. The P outputs are limited to 20mA.

Indeed so I always got a bit confused between F’s and P’s when doing Deltang programming. Would have been so much more helpful if the complete thing used a different letter for something that is different. But we are where we are.

I think, in my blog posts, I generally refer to the FET outputs as ABC and the P outputs as 1 - 8 to try and emphasise the difference.

Errrrr......?
So the motor outputs are H..
The buffered outputs are F..
And the logic outputs are P..

But in future, I will refer to buffered outputs, by the letter-designations 'A' to 'D'. - These are the FET buffered outputs, that can sink 2 Amps.

Oops oh dear sorry did not make myself fully clear! I meant in the instructions that left me going round in circles. In the end I did a logic table to help clear things up in my mind.
