Hi friend, I want to know if your circuit works without the connection of the PowerPAD GND? Because I will use the DRV 8816 without the PowerPAD GND connection Arthur
View ArticleRE: DRV8818: PPAD GND connection
Yes, it did, although I kept the current flow very low to avoid over-heating the chip. The conclusion is that the internal connection between PPAD and GND pins is adequate for at least low-current...
