9 Power Supply Recommendations

The DRV10974 device is designed to operate from an input voltage supply, VCC , range between 4.4 V and 18 V. The user must place a minimum of a 10-µF capacitor rated for VCC between the VCC and GND pins and as close as possible to the VCC and GND pins.

If the power supply ripple is more than 200 mV, in addition to the local decoupling capacitors, a bulk capacitance is required and must be sized according to the application requirements.
