Hello, looking for the datasheet of this IC: A2C44458 IC106 found on a drivetrain control module of a Jeep Grand Cherokee. The internet lead me that it's manufactured by Texas Instruments. But couldn't find any info about it... Any information would be helpful. I've attached a pic.

Thank you,

Surely you're joking?

Everywhere I've seen it for sale and looked at the pictures it's a QFN64. That post above looks more like an AI hallucination than anything which could be considered true.

Someone asked this chip in china ti support but nothing found there too. Some websites says its a amplifier audio chip For ECU Board(that doesnt really make sense to me) and some says for ECU injection repair that doesnt really make sense to me. Its a specialized chip for sure but maybe if you post the photo of the pcb we can guess its purpose.
