10 Power Supply Recommendations
The DRV8824-Q1 is designed to operate from an input voltage supply (VM) range between 8.2 V and 45 V. Two
0.01-µF ceramic capacitorS rated for VMA and VMB must be placed as close to the DRV8824-Q1 as possible. In
addition, a bulk capacitor must be included. If VMA and VMB are connected to the same board net, a single bulk
capacitor is sufficient.
