BOOSTXL-DRV8323RH is a 15A, three-phase brushless DC drive stage based
on the DRV8323RH gate driver and CSD88599Q5DC 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.

Hardware Files are on the BOOSTXL-DRV8323RH page within ti.com.
- For more details about the BOOSTXL-DRV8323RH, see the User's Guide for
the EVM.
- Make sure that the following
items are completed as described below, and then connect the BOOSTXL-DRV8323RH to J1/J3 and J4/J2 of the LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 as shown in Figure 3-10.
- Connect the motor, encoder, and
Hall sensors to the BOOSTXL-DRV8323RH and LAUNCHXL-F280025C, LAUNCHXL-F280039C, or LAUNCHXL-F2800137 boards as described in Table 3-2 and shown in Figure 3-10.
- Connect a supply voltage
ranging from 6 to 40 V from a battery or a DC voltage source to the
voltage supply pins as shown in Figure 3-10. The maximum supply voltage rating for the BOOSTXL-DRV8323RH is 65V, 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.
The switches and connections on
LAUNCHXL-F280025C as shown in Figure 3-11 can be used with the BOOSTXL-DRV8323RH, BOOSTXL-DRV8323RS , and DRV8353RS-EVMs.
