I'm looking to identify some ic's so i can order replacements based on the part numbers on the chips. I know i have a bq24072-bq24079 (well i was told) but cant make out what one. with some pins not matching it would help to have some key to decipher markings on chips.

Emmet,
First, you need to find out the top marking if the IC on the board;
Second step is to refer the PACKAGING INFORMATION on Addendum-Page 1
of the datasheet www.ti.com/.../slus937b.pdf and find which Device Marking matches the one on the IC. The marking represents the IC as shown by the table of PACKAGING INFORMATION.
Regards,
Eric

Thank you for that information. I had actually read through that PDF three times and totally missed that section. I will mark this as resolved thank you.
