mode
S1 = Right
Sleep mode
S1 = Left
Operating mode
B
External CSA output filter
RC output filter to
suppress high frequency
transients of CSA output
from current shunt.

2200 pF
F
c
~1 MHz
C
Power stage MOSFETs
and passive components
Optional passive
components for tuning
power stage, for example
series gate resistors,
RC snubbers, PVDD-GND
capacitors, PVDD-LSS
capacitors
R43, R44, R45, R49, R50,
R51 = 10 ohm
Series gate resistors
(GHA, GHB, GHC, GLA,
GLB, GLC)
R40/C10, R41/C11, R42/
C12, R55/C24, R56/C22,
R57/C23

PVDD-VDRAIN bypass
capacitor
C19, C20, C21 = 0.01 uF
PVDD-LSS bypass
capacitors
D
LDO jumpers
Jumpers to enable the
external LDO and disable
the LDO output. Remove
jumpers if DRV8328C/D is
used.
J8 = Populated
LDO is enabled
J8 = DNP
LDO is disabled
J16 = Populated
LDO outputs 3.3 V
J16 = DNP
LDO output removed
E
Dead time potentiometer,
jumper, & resistor
Jumper to enable
dead time control
from potentiometer and
potentiometer used to set
the resistance for DT pin
(DRV8328A/B only).
J14 = Populated
DT from pot is enabled
J14 = DNP
DT from pot is disabled
R99 (CW = more DT,
CCW = less DT)
Sets dead time of gate
outputs
R91
Fixed resistor for DT pin
F
HALL_PWR select
Use J6 to supply Hall
power from 3.3 V or 5 V.
J11 = AVDD
Supplies AVDD to Hall
power
J11 = EXT
Supply external hall power
from HALL_PWR_EXT
G
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
J15 = POT
VDSLVL set from
potentiometer
J15 = EXT
VDSLVL set from
VDS_EXT
J13 = Populated
VDSLVL is disabled (100
kΩ to GVDD)
J13 = DNP
VDSLVL is enabled
R92
Sets VDSLVL from 0.1
V-2.5 V
H
DRV8328 A/B or C/D
select
0-ohm resistors to
populate depending of
variant of DRV8328 used
on the EVM.
R1-R10 = DNP, R11 – R21
= 0-ohm
DRV8328A is populated
DRV8328B is populated
R1-R10 = 0-ohm, R11 –
R21 = DNP
DRV8328C is populated
DRV8328D is populated
