Touch Switch IC

[Rader2146]

That leaves the question of whether or not the IC is capable of transferring enough power. I can see it working fine with a power FET, but I would assume that the IC alone is probably not up for the high current.

I hadn't looked at the datasheet.

Hobbytronics didn't list a datasheet. Hmm..

Mamu, can you read the part # on the chip? I see that the one in the OKR video doesn't have the white "TOUCH" sticker on it.

Mamu, bridge the switch contacts on the DNA12 and use the touch IC to bridge pos or neg v-in, so the touch switch controls power, not the dna's switching circuit

Thanks for the suggestion Doug.

I bridged dna pins 1 and 2 and tried different configurations with that - connected to the ic and not connected. With what I tried, it was either always firing or not firing at all.

It was the same ic in both videos, I just took the sticker off before I had done the 2nd video to see the part #. It's 12F683

WillyB found the datasheet for it.
