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.
