I have an LED worklight with low- and strobe-functions.

One click: On - full Power
Two clicks: half Power
Three clicks: strobe
Four clicks: Off

The controller is circled:

No markings on the top so I desoldered it and found the markings on the bottom.

AT508CS (might be AT50BCS, but I don't Think so)
RBFKG1000
1904 X

Tried to identify the pinout: enter image description here

  • \$\begingroup\$ I can't find anything that fits the bill, but that may be a small 8 bit microcontroller. What is the pinout of that chip?(based on the traces on the board) \$\endgroup\$ – c10yas May 3 at 6:32
  • \$\begingroup\$ Hi. I tried to identify the pinout. The one that says "Signal out" is where the signal comes out from the chip. If i short the ones that says "Switch" if switches mode to the next. "In" is simply the in-pin. \$\endgroup\$ – Nickedemuz May 3 at 8:22
  • \$\begingroup\$ I'm inclined to say that it is simply a microcontroller. Anything that would implement modes like that would have to be an ASIC of some sort if it weren't a microcontroller. Then again, I see Chinese letters on the board, that along with the lettering on the bottom side of the component which I have never seen before could mean an ASIC that you can't buy off the shelf, designed and manufactured in mass just for this purpose \$\endgroup\$ – c10yas May 3 at 8:32
  • \$\begingroup\$ Why do you need a chip that implements that functionality? If you want to create duplicates it might be worth your time to use any SOIC-8 microcontroller and program it to do that \$\endgroup\$ – c10yas May 3 at 8:34
  • \$\begingroup\$ Thanks c10yas, I Think I'll do just that. It's completly new to me so it'll be fun learing how to do it :) \$\endgroup\$ – Nickedemuz May 3 at 8:43
