DRV10974 Operation Current Waveform Figure 19. DRV10974 Start-Up Waveform 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 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. 10 Layout 10.1 Layout Guidelines • Use thick traces when routing to VCC, GND, U, V, and W pins, because high current passes through these traces. • Place the 10-µF capacitor between VCC and GND, and as close to the VCC and GND pins as possible. • Place the 100-nF capacitor between VCP and VCC, and as close to the VCP and VCC pins as possible. • Connect GND and PGND under the thermal pad. • Keep the thermal pad connection as large as possible. It should be one piece of copper without any gaps. 10.2 Layout Example Figure 20. Layout Example |
