Looks good. I really like those PMOS from Vishay, pretty much my go to P-channel for switching power on and off. I've measured 2 mOhms with those at 3.7V, can't do much better than that (using voltage over current measurement). The TPS3700 is a great detector. I used it in my last project (non-ecig) and it works flawlessly, simple and easy to wire as well.

Wicked cool David. Time to order some more boards.

Thanks Craig. Really appreciate all of your help especially in this thread as well as the rest of the forum.
Thank you also dc. You considering making a similar board was what helped push me to make the board. Hope they work out well for you if you get some from Oshpark.

Im sure this board will work as good as your others. Ive been using your board with the fuses on it. It has worked great. Perfect in a G-box with a printed sled

Hi guys,
I've been running several unregulated single 3.7v IMR (20-30AMP max discharge) cell BF mods for while now with a single PSMN1R2-25YLC, is there anything better recently released in the SMD descrete 5x5x1.1mm package?
I ask only because i plan to make a few mods for friends and although I have had zero issues running 0.6Ohm coils I want to know why I should run more than one, incidentally they will be protected with MHP-TA15-9-77 , 15amp resetables between the battery negative and the source on the mosfet so will be tripping at around 60Watts assuming a 0.26Ohm coil and 4v.
Just because I haven't had issues doesn't mean others wont when a few are in the wild. I have though as stated had ultra reliable performance from the PSMN1R2-25YLC and they seem very resilient to slightly longer than ideal soldering periods.

I've got a board on eBay with a PSMN0R9-25 and 15K pulldown resistor already soldered on. It also has holes large enough for 14awg stranded wire for the Source/Drain high current lines and made with 2oz copper to reduce losses. I got reports of people using it at 0.08 ohms without it warming up at all.
qty 1 -

qty 5 with wire & heatshrink -

There are other listings including a qty 10.

Very nice Diyfl. I'm glad you and David4500 are doing those boards for the modders. I had one built a while back at oshpark but never got around to making it into a small package. Also if you're still around David, I have built and used 2 of your dualparamos minis and they are flawless.

I'm sure David4500 will see it. He's the one that invited me here and we've been sharing ideas and possible designs.

I'm getting back into playing with cads oft and diptrace and I wanna try to replicate your 2 boards but try to add in some form of modular design possibly adding pin header so you could kinda make it like a plug and play upgrade. Unregulated with plug n play pwm.

The key requirements I had for my board was as small as possible and 14 awg stranded for the high current wiring, and then I managed to squeeze in space for a through hole resistor for people that want to light an LED while vaping without having yet another dangling part.
A side effect of a clean through hole design, those people really needing high performance can parallel the MOSFET's just by stacking them.

Hey fellas! Yeah I still lurk around here from time to time... been a bit quiet lately... But anyways, TJ glad you like the boards. Making your own is much more satisfying, good luck.
