10.1 Layout Guidelines

  • Use thick traces when routing to the VCC, GND, U, V, and W pins, because high current passes through these traces.
  • Place the 10-µF capacitor between VCC and GND, and as close to the VCC and GND pins as possible.
  • Place the 100-nF capacitor between VCP and VCC, and as close to the VCP and VCC pins as possible.
  • Connect GND and PGND under the thermal pad.
  • Keep the thermal pad connection as large as possible. It should be one piece of copper without any gaps.
