10 Power Supply Recommendations
The DRV8307 device is designed to operate from an input voltage supply range between 8.5 and 32 V. This
supply should be well regulated. TI recommends using a minimum bulk capacitance of 47 μF to minimize
transients on the supply.
11 Layout
11.1 Layout Guidelines
For VM, place 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.
