I have designed an external IGBT ignitor board that has 4 channels. It uses the ON Semi ISL9V2040D3ST. This seems to be a very robust chip. During testing I ran this very hard and didnt have a single failure.
I ran this using a signal generator directly into the board, and also using the speeduino v0.4.3 board feeding it a crank signal from my signal generator, and had zero issues either way.
Using a thermocouple and a function generator, i saw stablized temps of 33.9*C at a simulated RPM of 6000 with a dwell of 3.5mS. The chips themselves have a operating range of up to 175*C, so it is still well within its operating range. It could use stick on heat sinks to be on the safe side.
The IGBTs themselves are also logic level, so they can be driven off of 5v signals just like a smart coil.
Here is my project page for this board. There is no BOM as it is only the IGBTs listed above, but i have also attached the gerber files if you wish to have the board produced.

Also, If you see anywhere there can be any improvements please let me know. I am still very new at this and may have missed something obvious.
*EDIT*
I have a bunch of bare boards i can send out if anyone would like to test one. I only purchased enough IGBTs for 2 full boards and i am keeping both for current projects. So if you dont mind purchasing the IGBTs and doing some basic SMD soldering i will send you a board for whatever shipping costs. Send me a PM if you are interested. All i ask in return is you let me know how it works out and if you have any issues with the product.
Thanks!
