I'm assuming you will change these ICs yourself and that's why you're asking. If you have access to the circuit board, then you should be able to find some numbers on the IC which you think is blown. If you can pull that IC and look at it's underside you may be able to find a number you can search on the internet for. Or you can find a number on the circuit board itself and maybe find the company that made that board and contact them to find out the IC you need. You can probably find an IC match as long as the pins are in the same order and the voltages are the same. Good luck!
