DRV8313: Thermal issues related to tying Pin 18 to ground?

Part Number:DRV8313

Hi,

I have a customer that is tying pin 18 (RSVD) to ground. They are experience the following and are wondering if it is because of this connection:

"As I power up  the board (no shorts measured) at about 1.1V it starts to pull current – with a IR thermometer the DRV8313 starts to get warm but ive current limited the supply to 0.1A to limit any damage – is this ground connection the issue?"

Any feedback would be greatly appreciated!

Thanks and regards,
Drew
