Help finding datasheet

[iXod]

It's a spindle motor controller on a Samsung HDD pcb: Marvell SH6125B. Out of production of course. Several sites say they have a datasheet but those link to datasheetcatalog or alldatasheet which have nothing.

Thanks.

Not a Marvell part. All pictures I can find of it show a TI logo.

HDD parts' datasheets are usually not public, unfortunately. Here's a list of others including yours, some with datasheets:

Depending on what you want to do, you might be able to find sufficient similarities with those.

Right you are!

Saw the hddoracle page. Not sure how to make use of those other IC data. If I don't have datashet of SH6125, not sure how to know what is similar/different.

Thanks for your reply.
