Table 4-2. Description of user selectable settings on DRV8311HEVM (H variant defaults in bold)
(continued)
Id. Setting Name Description Position Function
B GAIN select (DRV8311H only) Use J11
to select desired gain
settings. DNP jumper if
DRV8311H is not used. J11 = Bottom 0.25 V/A
J11 = Middle 0.5 V/A
J11 = No Jumper 1 V/A
J11 = Top 2 V/A
C SLEW select (DRV8311H only) Use J10
jumper to select desired
slew rate settings. DNP
jumper if DRV8311H is not
used. J10 = Bottom 25 V/us
J10 = Middle 50 V/us
J10 = No Jumper 125 V/us
J10 = Top 200 V/us
D MODE select (DRV8311H only) Use J12
jumper to select desired
PWM mode. DNP jumper
if DRV8311H is not used. J12 = Bottom 6x PWM mode
J12 = Middle 6x PWM mode
J12 = No Jumper 3x PWM mode
J12 = Top 3x PWM mode
E Power LaunchPad from
buck 0-ohm resistor used to
supply power from buck
to LaunchPad. DNP
if powering LaunchPad
externally see section _ on
MCU Power See section 3.4.4 MCU
power options
F Supply 5 V from
LaunchPad Supplies 5 V to some
of the EVM circuitry from
the F280049C LaunchPad
boost converter. R15 is populated Supply 5 V from
LaunchPad
R15 is DNP Supply 5 V externally from
TP23
G Supply 3.3 V from buck 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 TP22
H VIN_AVDD select Use J5 to supply
VIN_AVDD voltage from
either VM or 5 V. J5 = Left VIN_AVDD supplied from
VM
J5 = Right VIN_AVDD supplied from
5 V
I HALL_PWR select Use J6 to supply Hall
power from 3.3 V or 5 V. J6 = Left Hall power supplied
from 3.3 V
J6 = Right Hall power supplied from 5
V
J S/H/P variant connections Populate specific resistors
to properly use the SPI,
Hardware, or tSPI variant.
Populate R1, R8, R9, R10,
R11, and R13
DNP R12 and R41 SPI connections
