The IC looks similar to this; I found it on Google when searched for CT1668 HDA1144

CT1668

I don't even get the manufacturer name right; is it HEAD? Can anyone share its data sheet or at least some info on it? I couldn't find it on Google. Is HDA1144 the next version of HDA1134 shown in the image?

    \$\begingroup\$ The part number looks like CT1668 which is the same. Where did you get it from? You can check the function is matching the one in the description. \$\endgroup\$ – Eugene Sh. Mar 10 at 16:09
  • \$\begingroup\$ then what is the other number? I found it on my spoiled induction stove control panel. \$\endgroup\$ – Necktwi Mar 10 at 16:11

    \$\begingroup\$ The first number listed is usually the part number. Other numbers are sometimes lot numbers or date codes. A common date code is YYWW, where YY is the last 2 digits of the year, and WW is the week of the year. So, 1134 could be 34th week of 2011. \$\endgroup\$ – Mattman944 Mar 10 at 16:15
