Hi Rick,
I added a snubber consisting of a 10 OHM resistor and a 0.1 uF capacitor between PVDD and GND. But, I didn't see any ripple reduction from the DRV8432 output voltage. But, adding the snubber in paralled across a motor which is run by the output voltages reduced the output ripple voltage from 3V to 1V.
In the datasheet the snubber is added between PVDD and GND. Is the snubber used to maintain a good signal on PVDD instead of reducing the output voltage ripples? Do I need to add the snubber across the motor in order to reduce the DRV8432 output ripple voltages?
Thanks,
