Hello Guys,

I have implemented an FPGA design of a motor controller.. however the thing with the design that the FPGA itself cannot drive the motor as you need high current rates and so on.
Instead i got a board with an FPGA chip on it (runningthe digital design on the motor controller), and i have an analog circuit build of H-bridge mosfets + couple of amplifiers to drive the motors.

I am willing to convert my design into an IC chip.. my questions here for those of you who might know:
1- How do i combine both the analog and the digital parts into one IC? (meaning an IC chip that has the motor controller as designed in FPGA + an analog circuit with an H-bridge (or 3 H bridges actually) and few amplifiers.
2- Do you have any idea about costs? i am seeking into developing 500-1000 of the said ICs.
3- Do you know reliable companies who give support in this field?

Looking forward for your replies,
Joe

BTW yes i know there are ICs designed for this matter, but i require those special ICs for a start-up reasons.

I suggest talking to these guys: http://www.europractice-ic.com/ . They were very helpful when I was planning a similar project several years ago (in the end I determined it would be too costly and did not go ahead with it). Their latest price on a small order is 360 euros per square millimetre, with a minimum of 40 chips. They may be able to do better pricing on longer runs, but 1,000 isn't really enough to get a good price. Somebody other than me is likely to be able to give you a ballpark estimate of how much space your chip will require, but I'll just note that the high power mosfets you'll need to drive your motor won't be small.
