    Chip identification

    Hello everyone.

    I picked up a cheap kitchen liquidiser at the local flea market which perhaps unsurprisingly doesn't work. It has a remarkably sparse control board with one SOP 20 controller in the middle, which I cannot find any info on.

    If I'm not mistaken the number is TG49141AX07 with ATL1000 and 01 12 19 (date?).


    Any ideas as to where a datasheet might be found?


    Thanks in advance

    Have you measured anything? Can you tell us the Vcc voltage? (between pins #20 and #10 ?)

    Does this appliance have a transformerless power suply?

      I haven't measured any voltages but yes, it has a transformerless power supply.

      The next thread was actually going to cover this
