4.4.2 DRV8317S Compatibility

The DRV8317HEVM is compatible with the DRV8317S (SPI variant) to spin a 3-phase Brushless-DC motor. The DRV8317S replaces the hardware settings (MODE, SLEW, and GAIN) with 4 SPI signals: SDI, SDO, SCLK, and nSCS.

When using the DRV8317S, the DRV8317S variant IC needs to be soldered onto U1 in place of the DRV8317H, and resistors R9, R10, R11, and R12 must be populated with 0-ohm resistors. Additionally, the jumpers must be removed from J8, J9, and J10. This properly connects the SPI signals to the correct pins on the device.
