9 Power Supply Recommendations

The recommended voltage supply range for the DRV8662 is 3.3 V to 5.5 V. For proper operation, place a 0.1 µF low equivalent series resistance (ESR) supply-bypass capacitor of X5R or X7R type near the VDD pin with a voltage rating of at least 10 V.

The internal charge pump requires a 0.1 µF capacitor of X5R or X7R type with a voltage rating of 10 V or greater be placed between the VPUMP pin and GND for proper operation and stability. Do not use the charge pump as a voltage source for any other devices.
