11 Layout

11.1 Layout Guidelines

•

The VM pin should be bypassed to GND using a low-ESR ceramic bypass capacitor with a recommended

value of 0.1-

μF rated for VM.

•

This capacitor should be placed as close as possible to the VM pin on the device with a thick trace or ground

plane connection to the device GND pin.

•

The VM pin must be bypassed to ground using and appropriate bulk capacitor. This component must be

located close to the DRV8860.

11.2 Layout Example

Where the pull-up voltage (V3P3) is an external supply in the range of the recommended operating conditions for

the digital open-drain outputs.
