3.2 Connection Details

Figure 3-2 shows the power supply and motor connections made to the DRV8328AEVM in order to spin a 3-phase sensored or sensorless Brushless-DC motor.

A 4.5-V to 60-V power supply or battery is connected to the PVDD and GND terminals. The three phases of the BLDC motor connect directly to the OUTA, OUTB, and OUTC terminals of the screw terminal J12 provided on the DRV8328AEVM.

For sensored applications, to connect the Hall sensor outputs to the Hall connectors on the DRV8328AEVM, push down on the respective terminals to open the sockets and insert the Hall sensor wires into connector J10.

Figure 3-3 and Figure 3-4 shows where the Micro-USB cable is plugged in to the LAUNCHXL-F280049C to provide communication between the LaunchPad firmware and GUI as well as the correct installment of the DRV8328AEVM to the J1/J3 and J2/J4 headers of the LaunchPad.
