The DRV8316REVM provides
three half-H-bridge integrated MOSFET drivers for driving a three-phase brushless DC (BLDC)
motor with 8-A Peak current drive. The DRV8316 device integrates current-sense amplifiers
(CSA) for three-phase low-side current measurement and individual DC bus and three-phase
voltage sensing on the module that makes this board for BLDC/PMSM control with C2000

- The DRV8316REVM Hardware Design Files
are on the DRV8316REVM page within ti.com.
- For more details about the DRV8316REVM, see the DRV8316REVM Evaluation Module.
- Make sure that the following items are
completed as described below, and then connect the DRV8316REVM to J1/J3
and J4/J2 site of LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 as shown in Figure 3-15.
- If using DAC128S085EVM
board, bend J5-42 of the LAUNCHXL-F280025C 90 degrees to avoid connecting that pin to the DAC128S085EVM board. This EVM board is only used for debugging purposes to
monitor various software variables.
- Connect the motor, encoder, and Hall
sensors to the DRV8316REVM and LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 as described in Table 3-2 and shown in Figure 3-15.
- Connect a supply voltage ranging from 4.5
to 24V from a battery or a DC voltage source to the voltage supply pins as shown in Figure 3-15. The ABS max supply voltage rating for the DRV8316REVM is 40V,
so care must be taken to ensure that the voltage does not exceed this value during
operation. This is particularly important while slowing down or braking the motor, which
can cause the supply voltage to rise substantially. Power should only be applied when
instructed to do so in Section 3.5, keep disconnected otherwise.
