4.4 DRV8329AEVM Configurability Switch Functions
The DRV8329AEVM includes a variety of user-selectable jumpers and unpopulated components on the PCB to
choose user settings and evaluate the DRV8329A, DRV8329B, DRV8329C, or DRV8329D device. A summary
of those selectable settings is listed in
Table 4-2 (defaults in bold) and can be seen on the board in Figure 4-6 .
Table 4-2. User-Selectable Jumpers
Id. Setting Name Description Position Function
A nSLEEP switch Places DRV8329 in sleep
mode S2 = Left Sleep mode
S2 = Right Operating mode
B Dead time potentiometer,
jumper, & resistor Jumper to enable
dead time control
from potentiometer and
potentiometer used to set
the resistance for DT pin. J1 = Populated DT from pot is enabled
J1 = DNP DT from pot is disabled
R1 (CW = more DT, CCW
= less DT) Sets dead time of gate
driver outputs
R2 Fixed resistor for DT pin
C CSA input filter Input filter to filter
any Vsense switching
transients at the current
sense amplifier inputs. R45 = R43 = 0 ohm C30,
C31, C32 = DNP
CSA input filtering
D Power stage MOSFETs
and passive components Optional passive
components for tuning
power stage, i.e. series
gate resistors, RC
snubbers, PVDD-GND
capacitors, PVDD-LSS
capacitors R28, R29, R30, R34, R35,
R36 = 10 ohm Series gate resistors
(GHA, GHB, GHC, GLA,
GLB, GLC)
R25/C12, R26/C13, R27/
C14, R40/C26, R41/C24,
R42/C25 = DNP
RC snubbers
(HS FET A, HS FET B, HS
FET C, LS FET A, LS FET
B, LS FET C)
C18, C20, C44 = 2.2uF PVDD-VDRAIN bypass
capacitor
C21, C22, C23 = 0.01uF PVDD-LSS bypass
capacitors
G CSA gain select Selects the gain setting of
the integrated CSA in V/V. J2 = GND CSAGAIN = 5 V/V
J2 = 50 k CSAGAIN = 10 V/V
J2 = 200 k CSAGAIN = 20 V/V
J2 = DNP CSAGAIN = 40 V/V
H HALL_PWR select Use J6 to supply Hall
power from AVDD or
external hall power. J11 = AVDD Supplies AVDD to Hall
power
J11 = EXT Supply external hall power
from EXT HALL POWER
test point.
J VDSLVL potentiometer,
select and disable jumpers Potentiometer to set
VDSLVL between 0.1 ̶ 2.5
V, VDSLVL_SEL to select
voltage source, disable
jumper to disable VDSLVL J16 = POT VDSLVL set from
potentiometer
J16 = EXT VDSLVL set from VDS
EXT test point
J15 = Populated VDSLVL is disabled (100
kΩ to GVDD)
J15 = DNP VDSLVL is enabled
R74 (CCW = higher
VDSLVL, CW = lower
VDSLVL) Sets VDSLVL from 0.1 V ̶
2.5 V
K CSAREF select Jumper to select CSA
reference voltage from
AVDD or an external
reference source. J14 = AVDD CSAREF = AVDD
J14 = EXT CSAREF = CSAREF EXT
test point
L Speed pot Sets speed of the motor
when potentiometer is
enabled in the GUI. R73 (CW = less speed,
CCW = more speed) Sets duty cycle from 0%
to 100%.
