4.3 Connection Details
shows the connections made to the DRV8316xEVM to spin a three-phase sensored Brushless-DC
motor.
An 4.5-V to 35-V power supply or battery is connected to the VBAT and PGND terminals. There is a reverse
polarity protection implemented on the VBAT and PGND terminals. To bypass the reverse polarity protection and
pi filter implementation, R20 can be populated on the bottom of the board.
The three phases of the BLDC motor connect directly to the OUTA, OUTB, and OUTC terminals of the screw
terminal provided on the DRV8316xEVM.
To connect Hall sensor outputs to the Hall connector on the DRV8316xEVM, push down on the respective
terminals to open the sockets and insert the Hall sensor connections.
