DRV8353: Current sense output of the driver is ~1/4 of Vref at 0A current

Part Number: DRV8353

Hi,

I have a board with the DRV8353SRTAT chip.  I am looking at the current sense output, and it is outputting approximately 25% of Vref signal (expecting 50% of the Vref signal).

Voltages as checked:

-  Vref has been checked as 3.3V.  

-  The voltage across the input pins SPC to SNC is checked as 0V

-  The voltage of the output is ~900mV (should be 1.65V)

Can you recommend next steps for troubleshooting?
