IC database that can be searched by pin function

This is unrelated to the device selected above … more a generic question … I have been fixing things for 50+ years … with all the ic and discreet component databases out there for spice and or ecad programs, you would think that someone would have a database that is searchable by pin function … Just RE’d a no name scroll saw which has a speed controller with an IC top scraped off … board is discontinued … 14 pin IC has pin 2 as V+ and pin 3 as V- (very unique) … but have been unable to determine what this is. At other times IC’s and or other devices have burned up beyond recognition could be replaced if there were some way to search for pin functionality starting with power rails

Answer this question I have this problem too

Is this a good question?
