DRV8308
SLVSCF7A â FEBRUARY 2014 â REVISED OCTOBER 2014
10 Power Supply Recommendations
The DRV8308 device is designed to operate from an input voltage supply range between 8.5 and 32 V. This
supply should be well regulated. A minimum bulk capacitance of 47-µF should be used to stabalize the motor
voltage.
11 Layout
11.1 Layout Guidelines
For VM, place a 0.1-µF bypass capacitor close to the device. Take care to minimize the loop formed by the
bypass capacitor connection from VM to GND. Refer to the DRV8308EVM evaluation board for good layout
practices.
