DRV8353RS-EVM is a 15A, three-phase brushless DC drive stage based on
the DRV8353RS gate driver and CSD19532Q5B NexFETTM power blocks. The module has an
individual DC bus and three-phase voltage sensing as well as three low-side current
shunt amplifiers, making this board for BLDC/PMSM control with C2000 LaunchPad
development kits suitable for use with the sensorless InstaSPIN-FOC algorithm. The
drive stage is fully protected with short circuit, thermal, shoot-through, and under
voltage protection and easily configurable via the device's SPI registers
interfacing with C2000 MCUs.

Design Files are on the DRV8353RS-EVM page within ti.com.
- For more details about the DRV8353RS-EVM, see the User's Guide for
the EVM.
- Make sure that the following
items are completed as described below, and then connect the DRV8353RS-EVM to site 1 (J1/J3 and J4/J2) of the LAUNCHXL-F280025C as shown in Figure 3-13.
- The DRV8353RS-EVM connects on the bottom of the launchpad, so it
is necessary to use male to male adapters to connect the headers on the
DRV8353RS-EVM to the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 headers. The male adapter pins
corresponding to pins J1-17 and J1-19 of the DRV8353RS-EVM need to be disconnected from the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137. This can be accomplished by bending these
pins 90 degrees.
- Do not connect J3-29 and
J3-30 of the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 to the DRV8353RS-EVM as shown in Figure 3-13.
- Use a jumper wire to
connect J2-19 to J2-12 of LAUNCHXL-F280025C andLAUNCHXL-F280039C or J2-13 to J2-12 of LAUNCHXL-F2800137 to make proper connection of the C2000's
SPI-STE to the DRVx device as shown in Figure 3-13.
- If using the DAC128S085EVM board, bend J5-42 of the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 with 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 DRV8353RS-EVM and the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 as described in Table 3-2 and shown in Figure 3-13.
- Connect a supply voltage ranging
from 9 to 54 V from a battery or a DC voltage source to the voltage supply pins.
Power should only be applied when instructed to do so in Section 3.5, keep disconnected otherwise.
