No, that is the wrong type. I did not think to mention it when pilotdog68, but it must be a Schottky diode.
There are carts on page 2 of this thread. Those include an appropriate diode. While there are certainly better options on the market, the ones in those carts are the ones I’ve tested.
me too, it’s a real joy to follow these discussions.
So my next order will be SIR800DP…

This looks pretty usable for D1
I’m sure this is answered somewhere but I’m unable to find it atm.
Is the input of the voltage divider connected to Vin or to the output of D1?
Output of D1 would mean voltage monitoring with the Zener mod is not usable because the max input of the divider is the Zener voltage?
EDIT: rtfm - everything is in the 1st post
So this would be appropriate for D1?
Reading the datasheet, vF is about double the vF of the NSR0320. On the other hand its half the price.
Looks appropriate to me.
Sorry for highjacking this thread:
I’m currently fighting one(now 3 of these drivers) to get them running at >4V input.
Maybe some of you can take a look? A17DD Driver does not switch modes
is 0.58v at 1amp an acceptable rating for D1?
The diode doesn’t pass that much current to the mcu.
I know, but that’s the only Vf level that the mouser specs list.
It does seem on the high side. What’s it for? Many of the drivers listed in the Oshpark thread have carts listed or share similar parts lists.
It matches the Vf of a diode that wight recommended but at 1/3 the cost. It sounds high, but it’s in the lower Vf range of the diodes mouser has for sale.
With 3.67V on the driver input (while running) I measured 3.51V at the FET gate full on. At 2.99V I measured 2.833V. This is with the "ultra low vF" diode. It was pretty consistent at around 0.16V difference from input voltage to gate voltage. I need to swap in one of the cheap S4 diodes from the 105Cs and see what kind of drop I get from that.
Hi, these days I tried to study about A17DD-SO8. I find single side design a great feauture. I have some questions though.
How much is cost of this board, compared with classic 17mm fet blf fet driver? Except it’s single side design, does this board have advantages compared with blf fet?
it is zener ready
The cost is pretty much equivalent. It is easier to build and fits in more lights. The performance is equivalent.
Finges: there was already a specific zener mod FET driver. You could also easily modify the earlier revisions as well (but not the v1.0 versions without some modification).
I don’t do Windows. I was looking at cheap Windows laptops to program drivers and wondering what are the minimum requirements to program these and other boards. If you guys could suggest what is needed that would be a big help, thanks.
It wouldn’t take much at all, a $50 (used) netbook could probably manage it. They are very simple programs. Most of the tutorials are for windows, but a few people here do it in linux as well. That could be a cheaper option.
Any Windows laptop from the past ten years will do everything you need to program these drivers.
I don’t do Windows either. You can flash stuff from Linux if you like, and I have instructions available for setting it up in Ubuntu. You should be able to run it on pretty much any computer with USB, though on older ones you may need a lightweight version like Xubuntu.
I wonder if it would work in WINE in Linux?
AVRStudio might work in WINE, but why would you want to?
