Hi All,
I'm trying to identify a 8-pin IC (like a 555).
The marking is: BYL333
Can any one help?
Many thanks.

Re: 8-pin device ID help
Thanks RJ. I think it was switching some PNP's for some 12V LED arrays (for lighting purposes).
I have since bypassed this circuit and added a new controller.
Many thanks.Comment

Hi this is a really odd case.
I have removed all of the esd ic for USB 3.0 and 2.0
I measured all of the data lines and 5v usb voltage lines there are no shorts
all of the USB ports have no damage
Clearing the bios using the jumper wont help.
it is still showing USB overcurrent device
the only temporary fix I've tried and worked so far is flashing the bios
and the error is gone
but when you start the motherboard with a USB device still attached
the USB over current device error is back. the bios needs to be externally flashed... -
marking code 201 8pin ic
name or datasheet plz~

Hi all,
Wanted to share this as I couldn't find anything on the internet about this problem, so pulled one apart and found the problem myself. Years ago I bought approx 20 or so Crest Smart Home Single Power Adapter smart switches - small 240v Tuya-compatible (rebranded) smart switch devices with power monitoring, which Big W had on sale for half price. Paid $7.50 each for these, and they've been incredibly useful for turning things on and off remotely... and monitoring how much power each device uses.
However, after about 12 months, I had a number of these stop working... -
