10.1 Layout Guidelines
The VM pin should be bypassed to GND using low-ESR ceramic bypass capacitors with a recommended value
of 0.01-μF rated for VM. This capacitor should be placed as close to the VM pin as possible with a thick trace or
ground plane connection to the device GND pin. The VM pin must be bypassed to ground using an appropriate
bulk capacitor. This component may be an electrolytic and should be located close to the DRV8711.
A low-ESR ceramic capacitor must be placed in between the VM and VCP pins. TI recommends a value of 1 μF
rated for 16 V. Place this component as close to the pins as possible.
A low-ESR ceramic capacitor must be placed in between the CP1 and CP2 pins. TI recommends a value of 0.1
μF rated for VM. Place this component as close to the pins as possible.
Bypass VINT to ground with a 1-μF ceramic capacitor rated 6.3 V. Place this bypass capacitor as close to the pin
as possible.
Bypass V5 to ground with a 1-μF ceramic capacitor rated 10 V. Place this bypass capacitor as close to the pin as
possible.
