    Hello:
    I am reverse engineering a DC motor control circuit. It use 18 volts, two IRF7309 power MosFet, four 2N3906 low signal transistors, four diodes, two ferrite coils, and I am trying to figure out the circuit. Can anybody give me and idea of how the circuit shape could be (perhaps a similar design). It's controlled by a microprocessor output.
    Thanks in advance. My best regards.
    Rob

    Can you post a schematic to show what the actual circuit looks like? You can attach a .BMP or .JPG or .PDF or .DOC file.
