    Also on the BAT54S diodes, are these 3 pin? If so would someone have a full part number as I already have 2 pin ones.
    Any schottky diode of 500 mA 30 volts will be ok as a replacement.

    Every FDC6420C should be regarded as half bridge. It incorporate both the N & P channels mosfet.

    The circuit function is a driver for a bi-polar stepper motor with 12 volts @ 2 Amps max per winding.

    Cheers
