They look worth trying - not far from the spec. of the M542 series drivers. It depends if 50V is the absolute maximum voltage or recommended...

It's very interesting that a guy is testing THB6064AH,and he post the results there.It's good news for all that are interested in this kind chip with doubt like me.

Maybe I should have a try after he completes it.
