3 phase motor driver

[GregS]

I have been fishing through drivers hoping to find something.
Anyone know of a 3 phase mosfet driver module
with TTL in and the old board used a 170 VDC supply or rectified 120 line.
probably less than 10 amps. I have seen pieces, but
looking for an integrated module. The control circuitry
is intact in the device. Seems like the thing opperates around 20 kHz.
Must be isolated from TTL in. I can't say what the output
looked like or how sine or non sine the waveform was. Looked
like the old module used some sort of transformer coupling.

If you cant find something from IR then you will never find what you
are after. Look for the IRAMS series if they still exist.
