10 Layout

10.1 Layout Guidelines

Use the following guidelines for the DRV8601 layout:

  • The decoupling capacitor for the power supply (VDD) should be placed closed to the device pin.
  • The REFOUT capacitor should be placed close to the device REFOUT pin.

10.2 Layout Example

Figure 19 shows a typical example of the layout for DRV8601. It is important that the power supply decoupling caps and the REFOUT external capacitance be connected as close to the device as possible.
