what is this ic

[esinior]

hi, j have a 220v motor driver and i think it is a dimmer from its bt138 triac (it goes to a 220-24 trans and then to the motor) and its ic surface is erased and expunged and i don't know its number, does anyone know what this could be?

Manufacturers do that for a reason........

Reason is so you don't know ...plus elcheapo manufacture.
