Man…talk about being completely wrong…forgot about Richo 
So i take all i said about it being a TI part back.
The IC is a Richo - RP602Z330C
more info here n-redc.c o (dot) jp/en/pdf/mark/me-rp602z.pdf
Dimensions are inline with what i measured earlier.
Unrelated but, renesas appear to have a pin compatible part also on first glance
