I have some of the same drivers, except some work with clickies, and some work with momentary switches.
I want to convert the momentary to an inline switch, and noticed that the clickie driver had what I think is a FET, in place of a small resistor-like brown component that is on the momentary driver.
I believe it says A13HB on it. Where would I look for one of these? What kind of driver might have one that I could scavenge off of?
I have ten of these drivers that are all set for momentary switches and would like to convert them to inline. I can get them working, but only in one mode.
No way…looks like a NPN or PNP transistor, base, emitter, collector leads, SOT23 package unlike the 7135’s on the opposite side that have the 4 leads
That driver looks like it is divided into 3 separate 7135 channels (4 separate groups), ch2 being immediately to the right of the 8 pin MCU, channels ch3 and ch1 above on each side. (divide the driver like a 4 slice pizza and you will see the way the driver is chopped into “electrical” sections (the lower left quadrant is the “control” section)
I got my jewelers loop back out, and it’s a MOSFET, A1SHB. There was gunk on it and the S looked like a 3.
The best part is, I had a dish with three small dead drivers in it, and the first one I looked at had an A1SHB on it.
There are also two small empty solder pads on the momentary driver that has a small resister like component on the inline switch model. I don’t know what it is, but it says 103 on it, and there’s one of those on the dead driver too.
I hope those aren’t the components that are dead. I’m going to instal them tomorrow and see what happens.
The driver is 46”, and I have it in about five lights so far. Some are momentary and some are inline.
Today I took the momentary driver and reflowed the scavenged components and did the proper bridges so the driver was exactly the same as the inline version. I was hoping, but it didn’t work. All I could get was strobe.
