Like to know the complete Partnumber of an SO8 ST Chip

[AHage.2]

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, 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!​
