Yes, the TQ pin is used. The 30% torque reduction might be to low for some applications. The THB6064 has a better implementation for the current reduction.
This mounting style wich uses the PCB is used in a lot of drives from the Chinese up to AMC, Gecko etc.. It won't create problems.
Design is not yet finalised, I might publish the schematic when it is.
The PCB design can't be used for DIY, it's double sided and some pads are unaccessible for soldering on both sides, others will interfere with the chip mounting.

The THB6064(TB6564) appears to have been discontinued, since is not on the Toshiba website. In the USA Mouser has the TB6600 in stock at $7.50. The Cinese TB6600 boards have no schematics so you do not know what your getting and there is a 4 week delivery time.
