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.
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.
Setting | Jumper Position | Description |
---|---|---|
MODE | J10 = Top | 3x direct PWM Mode |
J10 = No Jumper | 3x PWM Mode | |
J10 = Middle | 6x direct PWM Mode | |
J10 = Bottom | 6x PWM Mode | |
SLEW | J9 = Top | 200 V/μs |
J9 = No Jumper | 125 V/μs | |
J9 = Middle | 50 V/μs | |
J9 = Bottom | 25 V/μs | |
GAIN | J8 = Top | 2 V/A |
J8 = No Jumper | 1 V/A | |
J8 = Middle | 0. 5 V/A | |
J8 = Bottom | 0.25 V/A |
