Is this the IRAMS-series chips with most of the driver integrated, and accepts TTL signals as input? I have a few of them which I could play with, but they don't have current limiting so an external current-sense resistor and amplifier is needed. It looked like this in 2006 when I thought I would have time to build my own AC servodrive... http://www.anderswallin.net/wp-content/2006_06servo/powerstage.jpg The IRAMS is bolted to the left side of the shiny heatsink.
