1/21/2013: Pulled two pages from Fairchild Application Note AN-9070 with a general application schematic and suggested PCB layout.

Initial Idea

Schematic isn't in eagle, but how about a breakout for the FNB41560/B2[1]
The schematic is Page 13 (Figure 15).
Just hook everything that goes to the MCU and the 15V, 5V, and phase current monitoring to a 100-mil header and use these[2] for the high-voltage V+, GND, U, V, and W lines.
Note that the high-power lines will have 15A through them.


Do you just want a breakout board, or did you want all those external components to also be integrated onto the board?
All the bootstrap caps, gate filters, sense resistors and at least a little (1uF-10uF film cap) main bus capacitance should be on the board. The idea is to make something you can quickly wire up to a high-voltage power supply and a MCU devboard to get a drive prototype working.
