Cannot find proper component needed. the chip im looking for has physical damage but i can still make out most of the numbers on it which are "54260 18F" the other numbers i believe might be "S101" but again the chip was physically damaged where the last numbers are. if anyone knows of this chip or where i can go to try and identify this component i would greatly appreciate it. the company that manufactures this device is refusing to release any schematics or diagrams with the information i need and i cannot find any information on the internet. please if anyone knows anything i could really use the help
