On a SO-8 chip, which has STmicroelectronics as the manufacturer, type "221" is stamped, but I'm unsure what the complete Partnumber is. Position in picture = "U7" It is used in a Tumbledryer.Can someone assist ? Thanks in advance !
hi Tesla.DeLorean, I guess you nailed it 100% !! identical picture!! And: orderable at my favorite Shop ;)Many thanks !!Now waiting for this to be delivered, and hopefully have a working tumble dryer after repair.
hi Tesla DeLorean, thanks a lot for your information, but the numbers on the chip are 221, not 211 as you refer to in the link from ST.I have found the LM221 from National Semiconductor before, but this 221 chip is from ST. Any other ideas?Thanks!
