I've come across an IC package type I can't identify, so help is appreciated. It's similar to a TSSOP-8, but the overall dimensions are smaller (3.1x2.0mm package). The relevant dimensions (in millimeters) are roughly:
Width: 2.2 (3.1 with pins, toe to toe)
Length: 2.0
Height: 0.7
Pitch: 0.5

It's not common for a company to use non-JEDEC listed packages, but not out of the realm of possibility. The markings on this particular one are "MH4", where the '4' is likely a date code, so "MH" is the marking code of interest. But without a proper package type, narrowing down the actual chip is challenging.
