Table 4-2. Description of user selectable settings on DRV8317HEVM (H variant defaults in bold)
(continued)
Id. Setting Name Description Position Function
B SLEW select (DRV8317H only) Use J9
jumper to select desired
slew rate settings. DNP
jumper if DRV8317H is not
used. J9 = Bottom 25 V/us
J9 = Middle 50 V/us
J9 = No Jumper 125 V/us
J9 = Top 200 V/us
C MODE select (DRV8317H only) Use J10
jumper to select desired
PWM mode. DNP jumper
if DRV8317H is not used. J10 = Bottom 6x PWM mode
J10 = Middle 6x direct PWM mode
J10 = No Jumper 3x PWM mode
J10 = Top 3x direct PWM mode
D Power LaunchPad from
buck 0-ohm R13 resistor on
bottom of board used
to supply power from
buck to LaunchPad. DNP
if powering LaunchPad
externally. See
Section
4.4.3 on MCU Power
See Section 4.4.3 on
MCU power options
E Supply 5 V from
LaunchPad 0-ohm R36 resistor on
bottom of the board
Supplies 5 V from the
F280049C LaunchPad
boost converter. R36 is populated Supply 5 V from
LaunchPad
R36 is DNP Supply 5 V externally (if
desired) from the+5V test
point
F Supply 3.3 V from buck 0-ohm R7 resistor
connects buck 3.3 V
voltage to supply main 3.3
V. R7 is populated Connects buck output to
supply 3.3 V rail
R7 is DNP Supply 3.3 V externally
from the 3V3 test point
G VIN_AVDD select Use J1 to supply
VIN_AVDD voltage from
either VM or 5 V. J1 = Left VIN_AVDD supplied from
VM
J1 = Right VIN_AVDD supplied from
5 V
H HALL_EXT select Use J2 to supply Hall
power externally or from
3.3 V J2 = Left Hall power supplied
externally from the HALL
PWR test point
J2 = Right Hall power supplied
from 3V3
I SPI variant connections Populate specific resistors
to properly use the
Hardware or SPI variant SPI variant: Populate R9,
R10, R11, and R12
J VREF connection 0-ohm R54 resistor
supplies CSA REF from
on-board VREF R54 is populated CSA REF is supplied
from on-board VREF
voltage
R54 is not populated CSA REF needs to
be supplied externally
through VREF test pin
