I added support for this driver but, out of the 3 I have ordered:

• Reverse half speed with a lot of heat.
  
• No reverse
  
• Both directions work perfect, but no current sense output.
  

So all three defective.  I am not very interested in this part anymore unfortunately.  Would have been a nice solution to reduce the needed solder connections.   It does make a lot of heat at 20khz ultrasound frequencies so must be run slower but maybe it it defective in this way too.

If anyone has fully working parts let us hear about it and where they were obtained.  I have no doubt good versions of this part will work.
