4.4.1 DRV8317H Compatibility
The DRV8317HEVM default is the DRV8317H (Hardware variant), which can be used to spin a 3-phase
Brushless-DC motor with selectable modes configured with hardware settings as shown in
Table 4-3 .
When using the DRV8317H, resistors R8, R9, R10, R11, and R12 must be left unpopulated. This allows the user
to select settings using the MODE, SLEW, and GAIN pins by using jumpers on J10, J9, and J8. An outline of the
various hardware selectable settings can be found below.
Note
In order to change the hardware settings for the GAIN, MODE, or SLEW using the appropriate
jumpers, the device must first be powered off or put into sleep mode in order for the new hardware
settings to take affect.
