Identify this chip please :)

Hi BLF,

I was wondering if anyone recognized this IC chip. It comes in a SOT-8 package in the driver for the Ultrafire Stainless Steel C3 and I was wanting to mod it.

Thanks for checking it out!

Also, are chips swappable? For example, would I be able get an Atmel chip, program it, and then replace the original one with it? Big Smile

Thanks scaru.

Has there anyone been able to program PIC chips?

I know Atmel chips have been reprogrammed (in the perfect modes thread) but how’s the progress with PIC’s? Smile

I'm pretty sure that PilotPTK uses PIC chips on his triple XM-L modules, it may be worth a shot asking him for advice.

Thanks a lot! Big Smile

Just looked it up and PilotPTK uses the PIC12F1840 chip.

Tido also has ported his firmware BLF-VLD to PICs like the 12F629. He planned to release a new version of BLF-VLD including the PIC port.

Thanks for your replies guys. Unfortunately it seems I fried the driver because I accidentally reversed the input polarity. I’m such an idiot. Sad

On the bright side, I’ve reassembled my C11 light sold here.

Because of the SMO reflector, the beam profile is horrible, but it throws pretty well.

Anyway, I noticed how there wasn’t any visible PWM in the med or low modes—I like it a lot.

Does anyone recognize this driver? I want to sense resistor mod it but have trouble finding where it actually is. (Does it even have one?)

Cheers! Beer
(BTW, I’m in love with this community; the amount of sheer friendliness is overwhelming!)

Little brownie above“DS” is a capacitor. Anything on the other side?

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?
