Well, if you have the device (part) in front of you, it would be very helpful if you took a legible photo of it.
If you only have the data sheet, then please upload either the URL to the data sheet or at least a complete page.

Ah, you're talking about the L9825. I have no information about its exposed pad, but it should indeed be connected to GND. This should be confirmed by a measurement between pin 1, 10, 11 or 20 to the exposed pad, which should give ~0ohm in each case.
If the problem is solved, please mark this thread as answered by selecting Select as best, as also explained here. This will help other users find that answer faster.
