Looking for footprint for ADP5052

What is the suggested land pattern for the ADP5052 in the CP-48-13 package? The document offered at http://www.analog.com/en/design-center/packaging-quality-symbols-footprints/package-index/csp-chip-scale-package/lfcsp.html only gives the dimensions of the package itself and not a footprint. Also, the link to AN-772 on this page does not work.

 

I've built a symbol for Allegro PCB Editor using ADP5052ACPZ-R7.bxl in Ultra Librarian, but am weary about using this since the output of Ultra Librarian rarely matches land pattern drawings (which I have none to compare to) in my experience. One possible mistake on this symbol is that the center pad has a soldermask that is a 1 mil square, which I suspect is a bit on the small side. Should the exposed pad not be soldered down?

 

Please supply a land pattern for this package.

 

Thanks.
