Really nice, as compared to a shunt and an isolated ADC and all that
stuff. Reasonably accurate, especially above 20c.

But they can't be serious about pushing 50 amps through an SO8

Their demo board thermal design is kinda silly.

Demo board makes sense to me. Simplest thermal conductivity
test.
They used 4 oz copper, hardly practical.
Why? The specialist printed circuit shops that make printed windings can cope with that and rather thicker layers of copper.
They mostly wasted the bottom layer thermally.
But you can't be bothered to tell us how they might have done better.
