Page: 9 / 23

The DRV8316REVM includes a variety of user-selectable jumpers and unpopulated components on the bottom
and top layers of the PCB to choose user settings and evaluate the DRV8316R/T device. A summary of those
selectable settings are listed in
Table 4-2 (defaults in bold) and can be seen on the board in Figure 4-5 and
Figure 4-6 .
Table 4-2. Description of User Selectable Settings on DRV8316REVM (default in bold)
Id. Setting Name Description Layer Position Function
A 3.3-V buck inductor User populates L1, L2, or R1 to
choose switching component for
buck regulator
Top L1 = 47 μH Inductor Inductor Mode
Bottom L2 = 22 μH Inductor Mode
Top R1 = 22 Ω Resistor Mode
B VREF/ILIM Select between using onboard
VREF or ILIM reference circuitry Top J1 = Left VREF
J1 = Right ILIM
C ILIM_SEL Selects ILIM voltage reference for
cycle-by-cycle current limit Top J2 = Left ILIM comes from MCU DAC
(R53 must be populated)
J2 = Right ILIM comes from R4/R7
voltage divider
D HALL_PWR_SEL Selects Hall power voltage Top J8 = Left Hall power comes from
3.3VBK
J8 = Right Hall power is provided
externally
E VREF select Selects VREF source Top R54 pop., R51 DNP VREF = 3 V from EVM
R54 DNP, R51 pop. VREF comes from MCU
F Rev. pol. Bypass Bypasses reverse polarity
protection and pi filter Bottom R20 is populated Bypass RPP and pi filter
R20 is DNP RPP and pi filter is used
G 3.3 V from
LaunchPad Connects buck voltage to
LaunchPad 3.3 V Bottom R13 is populated Connects 3.3VBK and
LaunchPad 3.3 V
R13 is DNP No connection between
3.3VBK and LaunchPad
3.3 V
H Center Tap Used to measure center tap
voltage of motor (R52 must be
populated) Bottom R33, R34, and R35
are populated Center tap voltage of motor
can be measured through
C_TAP test point
